Jonathan

12th Grade math Tutor • +37 Subjects

I am working as a Research Assistant at the Johns Hopkins School of Medicine in the Department of Transplant Surgery. Though I enjoy working in research, I truly love educating others in anyway that I can. My most recent tutoring experience was during the summer of 2014, in which I taught algebra to a middle school student. In high school, I tutored many of my peers in Spanish, mathematics, chemistry, psychology, and biology. I personally love tutoring both math and biology because the material is interesting and also fun to learn! As a tutor, I always try to relate the material at hand to specific interests of my student. I find that a student understands topics better when we find a way to equate his or her own hobby to the material. With that, I really seek out what the student enjoys doing and use their hobbies as positive reinforcements for learning. Personally, my interests include music (vocal and instrumental), sports, Harry Potter, superheroes, and juggling.

William

AP Calculus AB Tutor • +33 Subjects

I am passionate about. As a chemical engineering student at Vanderbilt University, I have always been passionate about learning math and science. I have also particularly excelled in these fields, perhaps due to my passion, and I managed to score a 790 on the math SAT and SAT II. I also took 5 AP Exams as a high school student, receiving 5s in Calculus BS, statistics, computer science, biology, and chemistry. At my university, I received an honors scholarship for my academic performance in engineering, and I currently aspire to continue my education at a higher level. As a tutor, I will motivate students, set clear goals, and help students progress towards a higher level of understanding.

Kimberly

11th Grade math Tutor • +84 Subjects

I am a recent graduate of University of North Carolina, Chapel Hill where I earned my Bachelor of Arts in Biology and Womens & Gender Studies. Having been a science nerd throughout high school, I knew that I would want to study biochemistry at university, but I also wanted to strengthen my writing, analytical, and research abilities in a non-scientific context. So focusing on both was perfect for me because I was able to develop analytical and problem-solving skills in two very different contexts. Having this background also allows me to feel comfortable tutoring a range of subjects.

Tarif

12th Grade math Tutor • +75 Subjects

I am a fourth year Medical Student in the Sophie Davis School of Biomedical Education at CCNY. This is a seven year BS/MD program, so by the end of the seven years, I will have achieved both degrees. I have a lot of tutoring experience in the K-12 age especially in the 7-12 grade range. I have taught SAT, SHSAT, ACT, SAT subject tests and Regents exams as well. My favorite subject to tutor is math and biology, but I am able to tutor other subject areas like reading, writing, chemistry, and physics. My tutoring style is very student oriented with some lecturing. I make sure that most of the time I am asking questions, even if it is basic, just to get the student to always be on his/her feet. I also make sure to use a lot of diagrams and flow charts when teaching. Outside of school, I spend a lot of time exploring and doing photography. I also love listening to music, watching basketball, and spending time with friends and family. Hobbies: books, photography, writing, reading, music, art

Taylor

4th Grade math Tutor • +67 Subjects

I am currently a lead preschool teacher. I received my Bachelor's in Psychology from VCU and am looking to return to school to further my education. While in college, I worked as a Supplemental Instruction leader, teaching general biology and anatomy. I have also worked in an after school program with elementary age children, but I have my fondest memories volunteering as a counselor for Camp Kesem. In my own experience, I loved school and now I love teaching even more at all age levels! I especially enjoy the challenge of getting creative to discover what approach and mediums work best for each student. I am available for in person as well as online tutoring.

Frequently Asked Questions

Students most commonly struggle with stoichiometry and balancing chemical equations—these require both conceptual understanding of how atoms rearrange and careful attention to numerical coefficients. Equilibrium and acid-base chemistry are also challenging because they involve abstract concepts that don't have obvious visual representations. Additionally, many students find the mole concept difficult since it bridges the microscopic world of atoms with macroscopic measurements, and unit conversions (especially when multiple conversion factors are needed) trip up even strong math students.

A tutor can help you see balancing equations as a conservation problem—atoms aren't created or destroyed, just rearranged. Rather than random trial-and-error, tutors teach systematic approaches like identifying the most complex compound first or using algebraic methods for tough equations. By working through the reasoning behind each step and connecting it to the law of conservation of mass, you develop the conceptual foundation to balance any equation, not just the ones you've practiced.

The mole is abstract because it connects three different scales: individual atoms/molecules (which we can't see), grams (which we can measure), and molar amounts (which we use in calculations). Many students memorize "1 mole = 6.02 × 10²³ particles" without understanding why this number matters or how to use it. A tutor helps by building the concept step-by-step—starting with how many atoms are actually in a small sample, then showing how the mole is just a convenient counting unit, and finally connecting it to real lab measurements and stoichiometric calculations.

Tutors help you see the full picture by explaining why you're doing specific lab procedures and how they connect to the calculations that follow. For example, in a titration lab, understanding the theory of acid-base reactions helps you predict the endpoint, while knowing stoichiometry lets you calculate the unknown concentration. Tutors can walk you through actual lab scenarios—how to interpret observations, troubleshoot unexpected results, and connect your experimental data back to the chemical principles you're learning in lecture.

The key is treating dimensional analysis as a logical puzzle where units cancel just like numbers do—if you set up the conversion factors correctly, the units guide you to the right answer. Many students struggle because they try to memorize which conversion to use rather than understanding that you're always multiplying by a fraction equal to 1 (like 1000 mL / 1 L). A tutor can teach you to write out every unit, cancel systematically, and check that your final units make sense, which prevents careless errors and builds confidence for complex multi-step conversions.

Tutors use multiple strategies to make equilibrium concrete: starting with simple physical analogies (like a bathtub where water drains and fills at the same rate), then progressing to particulate-level drawings that show molecules reacting in both directions simultaneously. Practice problems where you predict shifts in equilibrium help reinforce the concept, and connecting equilibrium to real applications—like how your blood pH stays constant or how industrial processes maximize product yield—makes it feel less abstract. Seeing equilibrium as a dynamic balance rather than a static state is the conceptual shift that clicks everything into place.

Strong General Chemistry students develop a systematic approach: identify what you know and what you're solving for, determine which concepts apply, set up the problem using dimensional analysis or stoichiometry, and always check that your answer makes chemical sense (not just mathematical sense). Tutors emphasize that the same core strategies apply across topics—whether you're calculating molarity, predicting products, or determining equilibrium concentrations. Building these transferable problem-solving habits early prevents you from feeling lost when new topics build on earlier concepts.

A true test is whether you can explain the "why" behind each step and apply concepts to new situations you haven't seen before. For example, if you can balance an equation you've never encountered, or predict whether a reaction will occur based on principles rather than memorized rules, you understand the concept. Tutors help by asking you to explain your reasoning, work through unfamiliar problems, and connect ideas across topics—if you can do these things, you're building genuine understanding rather than relying on memorization.
