Sharon

Pre-Algebra Tutor • +29 Subjects

I am a graduate of the University of Chicago, and I will be starting a graduate program at Columbia in August. I am about to complete a year of service with City Year, an education non-profit that places young adults into under-served schools. As a City Year member, I worked full-time in the classroom with middle-school students who were in approximately the 10th percentile for math (meaning they score lower than 90% of students). One-fourth of those students were able to grow around 15 percentile points by the end of the year! Hobbies: reading, cooking, gardening, music, art, nature, books, writing

I am a published author who has enjoyed “coaching” our daughter, as she navigated through high school, college and graduate school. I mentor college juniors who are seeking careers in financial services, and I serve as a peer resource to professionals who are transitioning from private industry to the nonprofit sector. Hobbies: reading, cooking, writing, books, music, art, travel

Tony

Calculus Tutor • +28 Subjects

I am a recent graduate of Yale University and incoming first year medical student at Columbia University. Originally from the DC area, I have always had a passion for science and medicine and pursued a degree in Biology while at Yale. During the 2008-2009 academic year, I tutored science, math, English, history, and Mandarin Chinese part-time with a DC-based tutoring company. At Yale, I worked as a freshman counselor to provide academic and career advice to incoming freshmen. I have taken both SAT and MCAT test prep classes and am familiar with both tests as well as the preparation necessary to score well. My personal career goals include attending medical school to pursue either immunology/infectious diseases or psych/neurology, teaching biology at the university level, and working in public/global health with either the CDC or the WHO.

Matthew

Pre-Algebra Tutor • +39 Subjects

I'm a highly creative person who works best with visual thinkers. Very recently graduated from Stanford University, I majored in Human Biology with a concentration in Bioinformatics and Stem Cell Science. Technical though my background may be, I am currently gigging as a singer/songwriter/composer in NYC and tackle even the most hard-science of problems with a top-down, big-picture, holistic approach. If you have a propensity to look at problems in a cross- or inter-disciplinary manner (or want to learn how to do so), I'm the tutor for you!

Quinn

Calculus Tutor • +17 Subjects

I am willing to address any issue with an open mind and I try to develop strategies that play to a student's strengths. I would like to think I am very approachable and personable, and I have had very positive experiences with many students in the past using this philosophy. Outside of academics, I love playing basketball and watching sports, as well as chilling with friends, listening to music, and keeping up with politics and current affairs.

Samuel

AP Calculus AB Tutor • +29 Subjects

I am a freshman at Caltech majoring in Applied and Computational Mathematics. My favorite subject to tutor is math because I find it very rewarding to simplify complex topics to aid in understanding. I have lots of tutoring experience. In high school, I ran and taught an SAT prep class and was vice president of my school's NHS chapter where I ran our tutoring program, and I, myself, tutored. I also was a teaching assistant in the summer of 2020 for a class in discrete mathematics through a program called PACT (Program in Algorithmic and Combinatorial Thinking). I love learning and hope to make the process enjoyable for you!

Frequently Asked Questions

Students typically find stoichiometry and limiting reagent problems challenging because they require multi-step reasoning and careful attention to mole ratios. Equilibrium concepts also trip up many students—understanding Le Chatelier's principle and calculating equilibrium constants demands both conceptual clarity and problem-solving precision. Additionally, thermodynamics and entropy often feel abstract until students connect them to real-world applications. A tutor can break these topics into manageable pieces, use visual representations, and provide targeted practice to build confidence in each area.

Lab skills are critical—the AP Chemistry exam includes free-response questions about experimental design, data analysis, and error evaluation that account for a significant portion of your score. Students need to understand not just how to perform experiments, but why certain procedures matter, how to identify sources of error, and how to interpret results meaningfully. Tutoring can help you develop strong lab technique, learn to analyze data critically, and prepare specifically for the types of experimental scenarios that appear on the exam.

Absolutely. Many students understand chemical principles but stumble on calculations involving scientific notation, logarithms (especially for pH and pOH), or unit conversions. A tutor can isolate the specific math skills you need—like manipulating the equilibrium expression or using the ideal gas law—and practice them in context so they feel less abstract. This targeted approach helps you build confidence with calculations without reviewing all of algebra.

Success on AP Chemistry requires different strategies for multiple-choice versus free-response sections. For multiple-choice, you need to recognize common distractors (like answers based on common calculation errors) and manage time efficiently—aiming to spend about 1.3 minutes per question. For free-response, showing your work and explaining your reasoning is essential, even if your final answer is wrong; partial credit is significant. A tutor can teach you to identify what a question is really asking, work backwards from answer choices when helpful, and practice pacing so you don't run out of time on the longer problems.

Taking full-length practice tests under timed conditions is the best diagnostic tool—they reveal which topics consistently trip you up and whether your struggles are conceptual or time-management related. A tutor can analyze your practice test results to pinpoint patterns (e.g., "you miss most equilibrium questions" or "you run out of time on calculations") and create a focused study plan. This targeted approach is far more efficient than reviewing everything equally and helps you maximize score improvement in the weeks before the exam.

AP Chemistry frequently tests your ability to read and interpret graphs—like titration curves, phase diagrams, and kinetics plots—and extract meaningful information from them. Students often memorize what a graph "should" look like but struggle when asked to explain why a curve has a particular shape or what it reveals about the chemistry happening. Tutoring helps you develop the skill of connecting visual representations to underlying chemical principles, so you can confidently answer questions about what a graph tells you and why.

Free-response questions require you to show complete reasoning and calculations, not just a final answer. Start by carefully reading each question and identifying what it's asking—many students lose points by not addressing all parts. Organize your work clearly, label units throughout, and explain your reasoning in words when appropriate; graders give substantial partial credit for correct methodology even if calculations contain errors. A tutor can teach you to structure your responses effectively, practice writing clear explanations, and manage the time pressure of completing all questions within the allotted period.

Consistent, spaced practice works better than cramming—aim for 4-6 hours per week spread across multiple sessions rather than one long cram day. Start with topic-specific practice problems to build mastery, then progress to mixed problem sets and full-length practice tests as the exam approaches. In the final weeks, focus on timed practice tests to build endurance and refine test-taking strategies. A tutor can help you create a realistic schedule tailored to your pace, identify which topics need more time, and adjust your plan based on practice test results.
