Hi students! I'm Maya and an incoming Sophomore studying Computer Science and Business at Cornell University. In high school, I took several AP courses such as APUSH, AP Calc AB and BC, AP European History, to name a few. I am more than willing to help out in any way I can. Please feel free to also check out my study guide website (myoutlines.com), which will soon have an iOS application (releasing this summer!) so students can study and review on the go.

I'm currently an undergraduate at Cornell University studying Biology. During a semester long break from working towards my Bachelor in Arts, I tutored Math to young students at Best In Class Education Center in Fort Bend, Texas. Prior to that teaching experience, I also tutored SAT Math. I was recruited shortly after taking the SAT myself, so it was a fresh and exciting experience for me. I currently tutor a variety of academic and test preparation subjects. I'm passionate about helping students because I have had some difficulty with certain subjects myself, and I understand the frustration of what that is like. My experience with High School Physics made me an advocate of getting help when it's needed. After seeking out assistance, I went from consistently struggling with the subject to graduating as Best Physics Student. I'm a firm proponent of the idea that with enough help, anyone can improve as drastically as I did. In my spare time, I enjoy painting, running and exploring.

I am a current sophomore at Cornell University pursuing a B.S. in Biomedical Engineering. I have done extensive coursework in biology, physics, chemistry, math, and lab sciences. I love applying engineering problem-solving skills to the biological sciences. For the past year, I have been a teaching assistant for introductory biology classes. In my free time, I participate in cancer immunotherapy research which focuses on melanoma.

I am currently a student at Cornell University. At Cornell, I have maintained a 3.88 GPA and made the Dean's List every semester. I attended a small private high school and graduated at the top of my class with a 4.0 GPA (unweighted). My ACT Composite score was 34, and I am an AP Scholar with Honors.I have developed effective learning techniques and study habits and my goal as a tutor is to pass these skill along to my students. I excel at explaining complicated ideas and problems in easy to understand plain English. On a personal level, I believe in the power of positive thought and I go out of my way to connect with my student and utilize positive reinforcement. I am passionate about teaching a variety of different subjects, including ACT and SAT preparation as well as English, history, economics, and mathematics.

I am currently a junior at Cornell University majoring in Human Biology, Health, and Society and minoring in Human Development. I took 13 AP, 6 Honors, and 3 college courses in high school. My strongest areas of study and teaching include Human Anatomy and Physiology, English, Nutrition, and Mathematics. I have previous tutoring experience and I am excited to start tutoring students of all ages.

I just completed my undergraduate degree in mathematics at Cornell University, with a minor in computer science. I will be pursuing a Master of Science in computer science at Cornell for the next two years. Teaching has always been a passion of mine, as has mathematics - and I am always eager to share this excitement with others.

I received a BA in Comparative Literature from Cornell University in 2013, and am currently working towards an MA in English at University of Connecticut. I have experience working with students K-12, as well as teaching First-Year Writing to undergraduates at UConn. I also worked for several years editing my college newspaper, and have additional experience in publishing. I specialize in teaching academic reading and essay writing, test prep and college readiness, and editing and verbal skills.I aim to understand each student's individual goals and approaches to learning, and gear my tutoring sessions to the student's particular needs. I find that we learn best when we understand the "why" behind the content, paired with practical and tangible methods. I have worked with students across ages and skill levels, and with a range of goals.

Cornell University Economics major with strong math skills through high school calculus. I focus on breaking down complex problems into clear, manageable steps while building confidence and independence. My experience supporting first-generation and low-income students has shaped my patient, encouraging teaching style. I am passionate about leveling the playing field and making math accessible and empowering for every student.

Scientific curiosity is necessary to inspire the next generation of young scientists. I did not begin to see the possibilities of scientific curiosity until I was 13, and only through a short summer camp. I did not feel very engaged in my science classes until sophomore year of high school, when I found a love for chemistry. Without the encouragement of my scientifically inclined family, I might have lost interest in science long before that chemistry class. As a woman, I hope young girls will be inspired to follow a path similar to mine. While women are 50% of the population, they are significantly underrepresented in STEM fields. I believe that there are many more women out there who might have followed a similar path to mine, had they been given the encouragement and inspiration that I had.Since high school, I have had the opportunity to work in several teaching environments including classroom work, one-on-one tutoring, and group work. In high school, I worked as a teaching assistant in my synagogue’s Hebrew school, where I worked with 3rd, 4th, and 5th graders. My senior year of high school, I tutored three home-schooled children in Hebrew, designing all lesson plans, activities, and tests. Between high school and college, I spent a year in Israel, as I knew engineering would make a semester abroad difficult. For three months of my time there, I volunteered in a grade school English class and after-school program for teenage kids in an underprivileged neighborhood. In the grade school, I sat in the class with the children, and helped them follow the lesson plan to enhance their learning experience. In the after-school program, I worked one-on-one with the students, assisting them with their math and English homework.In college, I had two major teaching experiences. My senior year, I worked as a workshop coordinator for freshman chemistry students. The purpose of the workshop was to give students an extra hour of work per week to enhance their understanding of the subject. I also came up with example problems and challenge problems to complement their homework and better prepare them for exams. My senior year I was a TA for a junior level chemical engineering course. The work was similar to the workshop I taught, with the added responsibility of grading. In graduate school, I worked one-on-one with several undergraduate students. I designed a presentation on data analysis to help them understand the best ways to present different types of data. In my 4 years at Penn State, I mentored and trained 7 undergraduate students to help them complete their senior theses and independent studies. For one year, I collaborated with a 4th grade teacher at a nearby elementary school to create and implement an active science curriculum. I designed experiments, activities, and thought exercises for the class to help them better understand scientific concepts of their curriculum.I completed my BS in Chemical Engineering at Cornell University and my PhD in Materials Science and Engineering at Penn State University. I am prepared to tutor students in Math, Science, and Engineering at nearly all levels. I especially enjoy Algebra, Calculus and Chemistry.

My personal goals for every moment of teaching are the growth of the student and the teacher. As one learns, as does the other. I will ensure that we will both learn and grow with each session.I first began tutoring in high school through Science National Honor Society and learned there that I love teaching others and began tutoring outside of school. Now here I'm in university and eager to teach while I'm learning.

I'm a Cornell University alumnus with a BA in Philosophy and Mathematics. My minor was Linguistics. Currently, I'm finishing an MSc in Logic from the University of Amsterdam. I tutor math, chemistry, logic, philosophy, English, Latin, and ACT prep. During my senior year, I was an undergraduate course assistant for Calculus I at Cornell, grading homework and conducting weekly homework study groups. I also taught courses on the philosophy of physics, mnemonics, and category theory to middle school students for a program called Splash. While living in Amsterdam, I was the TA for an introductory cognitive science course that included propositional logic and formal language theory. I took pride in giving highly detailed responses to students' questions, providing concrete examples and analogies to more familiar topics. My teaching philosophy is one of kindness, optimism, and patience. Also, I like to make my lessons as entertaining as possible, which is not difficult because I can be a goof even when it's not intentional. I can break complex topics down to their atoms. I never skip steps or assume that something is understood without confirmation. I try to see everything from your perspective. Most importantly, I work hard. I will go the extra mile to help you. Outside of the classroom, I enjoy writing stories and music. I spend about 2 hours every day exercising, and I love being outdoors!

I am passionate about empowering others to not only reach academic progress, but also gain a greater self-confidence through encouraging, patient tutoring. I am a middle school school STEM teacher seeking additional students to help in my out-of-work hours. Finally, I am a Cornell University alum and am confident in my ability to teach students in a range of fields - anything from English, ESL, art, writing, social studies to math and computers. Looking forward to hearing from you!Lena

i am here to boost your scores in math exams and standardized tests such as SAT, ACT and GRE.

I love tutoring and seeing students build confidence in their grasp of material. I enjoy tutoring Biology (Coursework, AP, SAT Subject Test) and Biochemistry because I love sharing my passion for "the study of life". SAT Math, SAT Writing, and SAT Verbal are my favorite subjects to tutor because I find it rewarding to see students feel more confident about a test that is nerve-racking for many. I believe in every student's capabilities to learn and improve. With my patience and motivating nature, I help students build confidence in their inherent abilities.In the last seven years, I have had a range of tutoring experience from being a Biochemistry Teacher's Assistant to teaching ESL classes online. I am a graduate of Cornell University with a Bachelor of Science in Biological Engineering. Since graduation, I worked as an engineer for more than two years. I am now preparing to go to medical school. In my spare time, I enjoying training for a half marathon, reading mystery books, dancing to Bollywood and Salsa music, and singing tunes that are stuck in my head.

I am a undergraduate student at Cornell University. I am studying computer science in the College of Engineering. I have been tutoring in all subjects since 9th grade, mostly computer science and mathematics and SAT. My teaching philosophy is based on hands-on learning, and the motto of 'practice makes perfection'. The more you face the problem head on and break it into smaller pieces, the easier the problem becomes to solve. In my spare time, I like to go outside on runs and play basketball with my friends

I have spent my life teaching math, both as a classroom teacher and as a tutor, and I love it! My goal is always to make mathematics simple and understandable. I teach by asking questions, both to check for understanding and to allow the student to figure out the concept on his/her own. While my favorite topics are Statistics and Trigonometry, I love teaching all of Algebra too. I have taught both AP Statistics as well as IB SL. Nothing compares to seeing the look of understanding a math concept on a student's face! In addition, I have taught courses in, and tutored, SAT Prep for 35 years. While I do tutor both the math and Reading & Writing sections, I do believe that students can be helped more in the math section. Therefore, I choose to work with students who want to improve their math score more, but may still want some help with the Reading and Writing. Yes, the SAT has changed throughout the years but I have kept up with it and have seen more than 100 SAT tests. I am an expert in SAT test construction and offer many problem-solving strategies for success on the SAT test.

I am a graduate of Fairleigh Dickinson University in NJ where I studied Marine Biology with a concentration in Biotechnology. I then enrolled in and completed a Ph.D. program at Cornell University in Toxicology with minors in Pharmacology and Immunology. My independent laboratory research conducted at Cornell focused on cellular changes that may lead to cancer. I then moved into the industry with multiple biotechnology companies and worked my way up from a bench scientist to a senior management role over the last 16+ years. I have worked to develop vaccines, gene therapies, and needed research reagents and tools. I bring to tutoring the experience and interactions I’ve had from being mentored and trained myself to the mentoring I’ve done to those I’ve supervised in their career development, including acting as an advisor to graduate students. I am passionate about science and enjoy tutoring all aspects of Biology along with Chemistry. I know the value of critical thinking, writing, and communication that is needed to be successful in school and beyond. In my spare time, I enjoy cooking, gardening, SCUBA diving, reading Sci-Fi and fantasy books, and spending time with my family.

I am a student at Cornell University studying Chemical Engineering and Computer Science. I'm living in Tarrytown right now and can help your son or daughter in math, science, or SAT/ACT prep! Over the past 5 years, I've accumulated many hours of tutoring experience. Some of the subjects I tutor include:-HS / AP Chemistry-HS / AP Physics-All Math Levels (Algebra, Trig, Precalc, Calculus, etc)- SATII Math (Both levels)-SAT / ACT Math- ACT ScienceOne of my core teaching methods is getting the student to thoughtfully approach questions and logically approach problems. I believe strongly that a student should be guided through problems rather than simply told whether they are right or wrong (that's what an answer key is for!). A tutor should provide feedback on their thought processes as well as follow through all possible choices when given options such as multiple choice. This way, students can learn to identify the right answer. My age gives me an advantage in that I have been in the shoes of all of my students not too many years ago. Not only do I currently use the information/skills that I help students acquire, but I believe I can act as a role model to encourage students that working hard pays off, and it is in fact cool to succeed in math and science. There is a huge reward for diligence, hard work, and success, and I try to instill these in every person I assist.My coursework has included Differential Equations, Multivariable Calculus, Discrete Math, etc. as well as lots of Physics courses (Heat and Mass Transfer, Mechanics, E&M, Fluid Mechanics), so you can be sure Physics and Math are my thing.Please consider me in helping you or your child, and I will do just that, to the best of my abilities.

A lifelong learner with multiple master's degrees and an undergraduate degree from Ivy League institutions, I bring my passion for learning to every conversation. I have tutoring experience in subjects such as AP U.S. Government and Politics, AP U.S. History, and college-level Political Science. I also have a professional background in data analytics, financial modeling, and statistical analysis, and can provide tutoring in any of those subjects. My teaching philosophy centers on fostering a supportive learning environment where students feel empowered to explore complex concepts and develop critical thinking skills. I prioritize connecting with students through engaging discussions and real-world applications, helping them see the relevance of what they are learning. I am motivated by witnessing their academic growth and confidence, and I enjoy incorporating technology and innovative approaches into my lessons.

As a passionate educator with a Master's degree in Statistics from Cornell University, I have over 2 years of tutoring and classroom experience in subjects such as Calculus, Linear Algebra, and Statistics. My teaching philosophy centers on fostering a supportive learning environment where students feel empowered to ask questions and engage deeply with the material. I believe that every student has unique strengths, and I strive to tailor my approach to meet their individual needs. Witnessing my students achieve their academic goals is what drives my passion for tutoring. Outside of the classroom, I enjoy exploring data visualization techniques and staying updated on the latest statistical methods, which I often incorporate into my lessons to make complex concepts more accessible and engaging.

I am an intelligent, creative education professional with a passion for Math, English, curriculum development, and intervention strategies. I am currently an Associate Teacher of Mathematics at The School At Columbia University, Columbia's independent K-8 school. Previously, I was an Academic Program Lead and Teaching Fellow at a middle school in East Harlem where I taught daily Mathematics Intervention classes and led daily Guided Reading instruction. I am also a trained and qualified SAT / SHSAT Tutor as well as a graduate of Cornell University in Ithaca, NY. When I am not at school, I love relaxing with my fiancee and our two cats - Biscuit and Pumpkin - at our home in Astoria, watching football, playing video games, going to the gym, and listening to all different kinds of music. I am really looking forward to helping you rise to your academic potential and getting you to the head of your class!

I am a recent graduate of the University of Kentucky with a Master of Science in Animal Nutrition. I received my Bachelor of Science in Animal Sciences from Cornell University. While I tutor various subjects, I am most passionate about tutoring math and feel that our school systems often fail students when it comes to math. I do not believe that some people simply "can't do math." I believe that some may need extra time and help, but everyone can do math. With patience and hard work, any student can learn. I also enjoy tutoring Spanish, which I have studied since I was in elementary. During undergrad, I even studied abroad in Barcelona and lived with a host family. In my spare time, I enjoy reading, dancing, TV/movies, and knitting.

I am senior at Cornell University majoring in Philosophy and Government with minors in Law and Society and Near Eastern Studies. Hailing from Central New Jersey, I have had years of tutoring experience mostly focusing on the liberal arts for all ages. My priority is to create an interactive and adaptive learning environment in which each session I can familiarize myself with the student's needs and habits. The student steers the lesson and lets me know how I can help and I do my best to ensure each lesson is tailored to them personally. Learning is a vulnerable and valuable experience, one which I am honored to play a part in. Please feel free to ask about the relevant courses I have taken at Cornell as well as my experience in high school as a National Honor Society tutor.

I'm a graduate of Cornell University, where I earned a Bachelor's degree in Chemistry & Chemical Biology with a focus on food science. After graduation I decided to take a gap year before applying for a graduate degree program and worked for six months at a winery internship in California. Over my high school and college years I tutored high school students in a variety of math and science topics, my favorites being Geometry and Chemistry. In my experience working with students who are struggling in math and science, I aim to help them develop their problem solving toolkit and build confidence in their academic intuitions. I also hope to pass on my passion for math and science to my students and make these often unpopular subjects more enjoyable. I'm a very visual learner and teacher, and I like to use charts, drawings, and physical models to help illustrate abstract concepts and make them more tangible and understandable. In this way, I've channeled my interest in chemistry into a love of food science, and in my free time I like cooking, reading, photography, and crafts.

I am a recent graduate of Cornell University, where I received a B.S. in Chemical Engineering and graduated Magna Cum Laude. Over the past several years, I have worked with students from diverse backgrounds and experiences tutoring thermodynamics (my personal favorite), chemistry, and math. I have also tutored in the past for ACT/SAT and other subjects such as history, but I am deeply passionate about science and engineering. I tend to push my students to understand conceptual topics, as opposed to rote or algorithmic learning. In my free time, I love to bake sourdough, learn about history, garden, and recently started biking again.

I first got into tutoring as a member of my high school's National Honor Society. The top students were encouraged to impart their knowledge through mandatory tutoring sessions. I found that I enjoyed helping others understand subject material and concepts. I felt like I was serving a greater purpose.Outside of tutoring I enjoy soccer, basketball, and ultimate frisbee. I am a big fan of the New York Yankees and New York Knicks. I am a sophomore at Cornell University, and I am planning to major in computer science.I sincerely believe that everyone is smart enough to understand everything, but each person needs a different amount of time and effort to get there.

Currently I am a graduate student in Stanford University's Master's Program for Human Genetics and Genetic Counseling. Prior to my enrollment at Stanford, I worked as a Genetic Counseling Assistant for Igenomix, a genetic testing laboratory. I graduated from Cornell University in December of 2021 with a BS in Biological Sciences and a minor in Education. As a student, I was a member of a research lab that works with the genetic basis of epilepsy in fruit flies as well as an undergraduate TA for a genetics laboratory course at Cornell. While I tutor a range of subjects, I am most passionate about tutoring biology and genetics, as that is where most of my expertise lies. I have enjoyed tutoring SAT and ACT math and science sections in the past and have found students have great success on these stressful tests after seeking out help from tutors like me. In my free time I love watching TV shows with my friends, being active, and painting. I am also a Crisis Text Line volunteer and enjoy taking shifts to help people through difficult times.

I earned my bachelor's degree in chemical engineering, then worked in the computer database software industry as a pre-sales engineer, consultant, trainer, and quality assurance engineer. Consulting in several industries gave me broad exposure to real-world problems and a work ethic that may serve as a role model. I learned to listen to problems and come up with creative and practical solutions. As a trainer and pre-sales engineer, I co-wrote a tutorial, created class materials, and made many technical presentations about "leading edge" software, and so became skilled at explaining complex concepts. My work in QA reinforced my obsession with quality and gave me a good eye for seeing and diagnosing errors, which applies to student errors and misunderstandings.I have tutored on and off since my college days, in math, science and ESL. I approach tutoring with a positive attitude, a good ear for listening, patience, respect, and humor. I have a bias toward deep understanding rather than rote memorization.

Hello! I am a Ph.D. student at the University of Texas at Austin studying Computational Science. I graduated cum laude from Cornell University with a B.Sc. in Computer Science.My doctoral studies fall at the overlap of mathematics, computer science, and physics. I enjoy coding software that adheres to professional coding standards but deals with solving complex physical problems. I have half a decade of experience coding in C/C++/Java. Some of the extensive projects that I have built include a microkernel in C, a puzzle video game in C++ and a compiler in Java.Over the past few years, I have tutored students in senior level college computer science courses in operating systems and computer vision. I enjoy teaching and I look forward to working with students who not only want to master the course material but also want to learn more about the subject.

I am a second year law student at the University of Chicago who hails from the San Francisco Bay Area! I tutor the SAT, ESL, and Spanish. I was an AVID tutor in high school, and after college I taught an ESL class and tutored a high school student in Spanish. In law school, I am involved with the Lawyers in the Classroom program. My tutoring philosophy is based on listening to students work through problems and helping them to spot their confusions or incorrect assumptions. I believe students learn much better when they aren't simply told the right answer or right reasoning; they need to get there on their own.Outside of academia, I love to sing. I'm classically trained, but I also participated in a cappella in college! I also ran my first marathon this year, and I love to cook and try new recipes.

I was a straight A student in high school, graduate Cum Laude from Stony Brook University, and went on to attend Cornell University for my MBA. Currently I'm a start-up consultant. I've always enjoyed teaching, however, that's why I like tutoring. I've a teaching assistant many times over, both in undergrad and grad school. I've also been a private tutor since high school. My goal is help you achieve, if not exceed your own. I believe in using a student's background and interests to help them understand concepts they may not grasp upon first review. I'm always available as a resource online when there in person. I really do enjoy tutoring, and I can't wait to be yours.

After graduation, I joined a rotational leadership development program which has allowed me the opportunity to expand my knowledge into many industries and functional areas, as well as work with colleagues from around the world.Throughout my life, I have been passionate about learning, and have shared this love for learning through teaching. My first experiences of teaching came early in life, when a teacher recommended that I use my mastery of content and easy way of explaining material to tutor fellow students after school. From those first moments of realizing the enormously positive impact I could have in a student's ability to master content, I have always incorporated teaching into my life. In college, I tutored extensively in fundamental engineering courses, and conducted workshops to further strengthen my students' understanding of the material. Standardized testing is one of my strong suits, and I enjoy helping students advance in their performance in Critical Reading, Math, and Writing.I believe a strong foundation in education is vital for future success. I've had wonderful opportunities because of my strong educational background, and I try to impart this appreciation to all my students. In my spare time, I enjoy teaching dance, playing music, and traveling throughout the US and the rest of the world.
