Rhea
AP Statistics Tutor • +49 Subjects
I am a current student at the University of Chicago. I am working towards a Bachelor of Science in Biological Sciences, and I am on the pre-medical track. I am extremely passionate about tutoring, and I have several years of experience tutoring students in my high school's learning center in various subjects as well as tutoring private clients in Standardized Test preparation. Given that I graduated high school recently, I have taken several Standardized Tests and high school subjects myself, so I have a comprehensive understanding of not only how to tutor these subjects and exams, but also what it is like to take them. While I have a wide range of interests and am able to tutor various subjects, I am most passionate about tutoring in Standardized Test preparation (including ACT, SAT, SAT Subject Tests, and AP Exams), Biology, Chemistry, Math, and Spanish. I truly believe that students should have the opportunity to learn in the way that works best for them, and I love being able to help them succeed by creating a comfortable tutoring environment in which we can best assess their particular needs and use strategies specific to them. My passion for learning drives everything that I do, and tutoring is the platform that I use to try to spread that passion to others. In my free time, you can find me playing badminton, listening to music, or baking something (hopefully) delicious.
Jeffrey
Pre-Calculus Tutor • +29 Subjects
I am enrolled in the Mechanical Engineering PhD program at Rice University which will begin Fall 2020, and I am hoping to return to academia as a professor after earning my PhD. In the meantime, I am looking to share my passion for gaining knowledge, specifically in STEM, by educating the up and coming members of such a great field. I have experience tutoring both Calculus and Physics at Notre Dame, as well as experience as a Student Assistant for Differential Equations and Mechanics. I believe the key to learning is much deeper than learning to solve problems and that seeking knowledge is one of the best means for personal improvement.

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
Annie

I am currently a second year medical student. I was a Physiological Sciences major at UCLA (class of 2015), and pursued research during my gap year between undergrad and medical school.
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

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!
Charles
AP Calculus AB Tutor • +25 Subjects
I am a junior Mechanical Engineering major at Yale, and I hope to become a Naval Aviator after college. I am also a varsity sailor, and enjoy playing music with friends when I can get some free time. I have been tutoring my fellow students throughout my entire academic career, and I would best describe my tutoring style as one that adapts to each students' needs. For example, I have always tried to frame questions in a different way so that the student can better understand the question. Some students need visual representations of numbers and systems to understand them, and others benefit more by understanding the concepts behind each formula. I prefer to tutor in math and physics, and especially with real world application problems. I hope to help students improve their standardized test scores and their understanding of the math and sciences so that they can achieve their academic goals! Hobbies: art, books, running, reading, music, writing

Frequently Asked Questions
Students often find photosynthesis and cellular respiration particularly difficult because they require understanding complex electron transport chains and energy coupling—concepts that are abstract and easy to confuse. Genetics and evolution topics also challenge many students because they involve multiple interconnected concepts (Mendelian inheritance, population genetics, natural selection) that must be understood simultaneously. Additionally, the ecology unit's quantitative aspects, like calculating population growth rates and energy flow through trophic levels, trip up students who aren't as comfortable with mathematical reasoning in a biology context.
The exam has two main sections: 60 multiple-choice questions (90 minutes) and 6 free-response questions (90 minutes). For the multiple-choice section, you need to practice identifying which concepts are being tested and avoid common distractors—many questions test whether you understand *why* something happens, not just *what* happens. For free-response questions, you'll need to write clear explanations using proper biological terminology and often include diagrams (like Punnett squares or energy pyramids). Tutors can help you develop a strategy for time management, since many students rush through calculations or skip labeling diagrams, costing them easy points.
Lab skills and experimental design are critical—the exam heavily tests your ability to design experiments, identify variables, and interpret data. Many free-response questions ask you to design an experiment to test a hypothesis or analyze results from an unfamiliar lab. Students often struggle with identifying the independent and dependent variables, controlling for confounding factors, and explaining *why* a particular experimental design would work. Tutors can walk you through classic AP Biology labs (enzyme kinetics, photosynthesis, cellular respiration, gel electrophoresis) and teach you the framework for designing sound experiments that actually answer the question being asked.
You'll need to calculate allele frequencies using the Hardy-Weinberg equation, determine population growth rates, compute energy transfer between trophic levels (typically 10% efficiency), and work with chi-square tests for genetic crosses. Many students underestimate the math component and get tripped up by simple calculations or misinterpreting what a number means biologically. For example, understanding that a chi-square value tells you whether your observed data significantly differs from expected ratios is just as important as calculating it. A tutor can help you practice these calculations in context so you're not just plugging numbers in—you actually understand what the result tells you about the biology.
AP Biology vocabulary is dense, but memorizing definitions alone won't help you apply concepts on the exam. Instead, focus on understanding how terms connect—for example, how photosynthesis, chloroplast structure, thylakoid membranes, and light-dependent reactions are all part of one system. Tutors often teach vocabulary through concept mapping and by repeatedly using terms in the context of explaining mechanisms (like how chemiosmosis works in both photosynthesis and respiration). Practice explaining concepts aloud without looking at notes, and when you encounter a term you don't know on a practice test, trace it back to the biological process it describes rather than just looking up a definition.
Practice tests are most valuable when you take them under timed conditions (90 minutes for each section) and then spend significant time reviewing every question you missed—not just the ones you got wrong, but also the ones you guessed on. For each mistake, identify whether you lacked content knowledge, misread the question, made a calculation error, or ran out of time. This pattern recognition helps you prioritize what to study. Many students make the mistake of taking practice tests too early or too late; ideally, start full-length practice tests about 4-6 weeks before the exam so you have time to address weak areas. A tutor can help you analyze your practice test results to identify whether your struggles are conceptual, strategic, or time-management related.
Read the question carefully and underline what it's actually asking—many students lose points by answering a slightly different question than what was asked. For questions that ask you to explain, design, or predict, organize your response with clear topic sentences and use specific biological evidence (e.g., "because ATP provides energy for active transport" rather than just "because of energy"). If the question includes a scenario or data set, reference it directly in your answer. Graders award partial credit generously, so even if you're not 100% confident, write what you know using proper terminology. Tutors can teach you the common free-response question formats (explain a mechanism, design an experiment, interpret data, make a prediction) so you recognize patterns and develop a reliable approach for each type.
Score improvement depends on where you're starting and how consistently you engage with tutoring and practice. Students who start in the 2-3 range and work steadily often reach 4-5 within a few months, while students already scoring 4s typically need targeted work on specific weak areas to push into the 5 range. The most significant gains come from understanding *why* you're missing questions (content gaps vs. test-taking strategy vs. time management) and addressing that root cause. Consistent practice with feedback—where a tutor helps you identify patterns in your mistakes—is more effective than cramming or passively reviewing notes. Expect meaningful improvement if you commit to 5-8 hours per week of focused study over 8-12 weeks before the exam.
