I am a graduate of the University of Chicago, with a bachelor's degree in psychology and linguistics. Currently, I am pursuing a master's degree in speech-language pathology at Teachers College, Columbia University. In the past, I have worked as a teacher's aide in a public school classroom, a mentor to middle school girls, an instructor and tutor at the literacy education organization 826, and a summer camp counselor. I tutor a diverse range of subjects, and I find that I especially enjoy tutoring language arts, reading, and writing at all levels, from elementary school all the way up to college/grad school test prep. As a tutor, I am committed to helping students reach their full potential as learners. Throughout my years as an educator, I have seen firsthand the remarkable academic growth that can occur when tutors provide students with the individualized support that they need. In my spare time, I enjoy reading, journaling, and learning about other languages and cultures.

I am a driven, positive, affirming tutor who is happy to help students in any way he can. I graduated magna cum laude from Dartmouth College in 2020, and I obtained my Master's in Political Science from the University of Toronto in 2022. In 2016, I received an SAT score of 1550. That year, I also received a 5 on my AP exams in Calculus AB, English Language, U.S. History, and U.S. Government. I am happy to tutor students in mathematics, English, and social sciences (e.g., history, government). I especially enjoy tutoring pre-algebra and algebra. I believe in a practice-based approach in which I take students step-by-step through the concepts at hand. After practicing together with my guidance, the student will soon be able to apply what they have learned on their own.
I am a new graduate of Pomona College, in Claremont, CA, where I studied Religion and Philosophy. While there, I wrote many papers of a wide variety, working on strong arguments, organization, and phrasing. I peer edited as well as volunteering with groups that mentored high school students, focusing on college admissions work, continuing and expanding my experiences from high school of tutoring for standardized testing. Additionally, I taught beginning violin to younger children.
I'm a current medical student at the University of Arizona College of Medicine with undergraduate degrees from Washington and Lee in chemical engineering and anthropology. I have extensive experience in tutoring and teaching since 2010, and am ready to help you with your learning needs! I focus on standardized testing (SAT/ACT) and also tutor in a wide range of math, English, and Spanish classes. In my free time, I like to run, do CrossFit, volunteer, and watch TV!
I've been working with students for over seven years, from middle school all the way through college, across subjects like math, calculus, statistics, linear algebra, chemistry, and physics, with a lot of SAT and ACT prep mixed in. My background is perhaps a little unconventional. I have two bachelor's degrees, one in Engineering and one in Communication Studies, plus a Master's in Design. That combination means I can guide you through challenging technical material and communicate it in a way that is easy to grasp. What I care most about is helping students get to a place where they don't need me anymore. I know that sounds like a strange thing for a tutor to say, but I think it's the right goal. I'm not here to walk you through steps to copy down. I want you to understand why something works, because that's what holds up under pressure, on a test you haven't seen before. If you're ready to ace that test or prove that theorem that's been bugging you, reach out and let's work together
Preparing for the SSAT means building skills across verbal reasoning, quantitative math, and reading comprehension simultaneously — which can overwhelm students without a clear plan. Yoonseo creates a structured study schedule that rotates between analogy practice, arithmetic and algebra drills, and timed passage work so no section falls behind. Her years teaching both math and English at Kumon make her unusually comfortable covering every part of the exam.
I am a member of the Brown Class of 2018, pursuing a bachelors degree in mathematics. I graduated from Phillips Exeter Academy in 2014. (I am able to help anyone with the boarding school admissions process.) Outside of academia, I pursue my passions in dance, travel, volunteering, reading and art. My tutoring subjects are mathematics (from elementary school to college level) and standardized testing (SAT, SAT subject tests, PSAT, and SSAT). I have tutored mainly high school students in the New York State Regents exams and AP Calculus, although I also have experience with students in middle and elementary school. Since I have been through many school systems, including public, private, studying abroad, and boarding school, I have learned many different techniques and can attack a problem from various angles. Ultimately, my teaching style is full of tips and tricks to break down complicated topics into simple, more understandable ideas.
I am a recent graduate from a masters program in biostatistics at Columbia University. I received my Bachelor of Arts in biological sciences, with a focus in neurobiology at Northwestern University. In August, I will be starting a doctoral program in biostatistics at NYU. I was a teaching assistant at Columbia University in my department and also have tutored graduate students and undergraduates privately as well. My primary areas of tutoring are math and statistics coursework in addition to math sections on standardized tests such as the GRE and GMAT. I am very passionate about helping students feel more confident and excited about math. In my spare time, I enjoy running, playing piano, and spending time with friends and family.
I hold a Bachelor's degree in Applied Mathematics and Statistics and Economics from Johns Hopkins University and a Master's degree in Biostatistics from Boston University. My academic background has given me a strong foundation in both quantitative reasoning and analytical thinking, which I bring into every tutoring session. I'm passionate about helping students build confidence in their abilities and enjoy guiding them through challenging material by breaking down complex concepts into clear, understandable steps. With over five years of tutoring and teaching experience, I've worked with students across a wide range of subjects, including middle school math, Algebra I & II, Geometry, Precalculus, AP Calculus AB/BC, AP Statistics, and college-level courses like Calculus IIII, Linear Algebra, Differential Equations, and Statistics. I also specialize in standardized test preparation, offering targeted support for the SAT, ACT, and GRE math sections. Beyond math, I tutor economics at both introductory and advanced levels, including Introductory Microeconomics and Macroeconomics, Microeconomic and Macroeconomic Theory, Monetary Analysis, and similar courses. I enjoy helping students connect theoretical models with real-world applications and develop a strong understanding of core economic principles. My tutoring style is patient, supportive, and highly personalized. I focus on fostering deep understanding and critical thinking, tailoring my approach to fit each student's individual learning style and academic goals. Outside of tutoring, I enjoy reading, staying active, and exploring emerging technologies.
I am a Yale graduate with over 8 years experience tutoring students from a variety of backgrounds. I recently graduated from the Yale School of Public Health with a MPH concentrating in Epidemiology and Global Health. I also received my B.S. from Yale with a double major in Molecular, Cellular, and Developmental Biology and French. I have experience both leading group classes and working with students one on one. I will respond to a student's strengths, weaknesses, and learning style in order to help them succeed and make the most of our time together. I earned a perfect score of 36 on the ACT, 2280 on the SAT, and qualified as a National Merit Scholar on the PSAT. I look forward to working with you!
No subject, no test, and no question is bigger than you. By the end of our time together, I hope to make you see that my only job was really just to make you see--you really had it in you, all along. If there's any subject in which you truly believe you suck--that you're just the worst, and that nothing will ever help you improve--then don't you dare give up until you've given me a call! I'm a writer, but I love numbers, and nothing makes me more proud than helping students overcome their biggest challenges. I've scored near-perfect on both standardized tests, and I've been helping students understand how to improve their own scores ever since. I'm also capable of tutoring advanced Music Theory topics, as well as Spanish and Mandarin Chinese
I'm eager to teach students how to make connections and understand any part of the world they need!

Frequently Asked Questions
Score improvement depends on your starting point and study timeline, but most students see meaningful gains with focused preparation. Students who work with tutors for 8-12 weeks typically improve by 50-150 points, with some seeing larger jumps if they're addressing specific skill gaps. The key is identifying exactly where you're losing points—whether that's pacing on the quantitative section, inference questions in reading, or sentence completion problems—and targeting those areas strategically.
Reading comprehension and the upper-level verbal section challenge most students because they require both fast reading and deep understanding of nuanced questions. The quantitative section often trips up students on pacing—they get bogged down on hard problems and run out of time for easier ones later. A tutor can help you develop a strategy for each section: learning to predict answer choices in verbal, spotting trap answers in math, and managing your time so you're not rushing through questions you could get right.
Timing strategy is crucial—the SSAT isn't just about knowing the material, it's about getting the most points in the time you have. Many students waste valuable minutes on difficult problems early on and then rush through easier questions at the end. Tutors help you learn when to move on from a hard problem, how to allocate time across sections, and specific techniques like skimming vs. close reading for different passage types. With the right pacing plan, most students gain 10-30 points just from better time management.
Test anxiety often comes from feeling unprepared or not trusting your skills under pressure. Working with a tutor builds confidence through repetition and success—you'll take dozens of practice questions and full-length tests, so the real test feels familiar rather than scary. Tutors also teach you concrete strategies for the test day itself: breathing techniques, how to manage time so you're not panicking, and how to recover if you hit a hard section. When you've practiced the timing, know your weak spots are addressed, and have tested yourself many times, anxiety naturally decreases.
Taking 4-6 full-length practice tests under timed conditions is ideal, with spacing between them so you have time to learn from each one. The first practice test helps you establish a baseline and identify weak areas. Middle tests let you practice new strategies and see if they're working. Your final tests should feel like dress rehearsals—same timing, same setting, same pressure. A tutor will help you review each practice test strategically, focusing on the patterns in your mistakes rather than just going over the answers.
The writing sample is your chance to show schools how you think and express yourself—it's less about perfection and more about clarity and organization. You'll have 25 minutes to write one essay on a prompt, so practice is essential. Tutors help you develop a quick planning process, learn how to write a clear thesis with supporting examples, and practice writing under time pressure. The goal isn't to write like a novelist; it's to write a coherent, well-organized essay with specific examples. Most students improve significantly by practicing 8-10 timed essays with feedback.
A typical preparation timeline is 8-12 weeks, with 5-8 hours per week of focused study. This gives you time to learn the question formats, build skills, and practice under timed conditions. If you're starting from a lower baseline or aiming for a very high score, 12-16 weeks may be better. Starting earlier also reduces stress and prevents last-minute cramming. A tutor can create a personalized study plan based on your goal score, current skills, and test date, then adjust it as you progress.
