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.

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 passionate about teaching and tutoring and I thoroughly enjoy helping students gain an understanding and a drive for their studies. I have a long history of working with students of all grade levels and abilities (elementary school through college), and I have a good understanding of strategies to excel in both general academics and standardized tests.
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.

Frequently Asked Questions
Students typically find the interconnected nature of APES most challenging—especially understanding how systems like biogeochemical cycles, energy flow, and population dynamics interact across different biomes and ecosystems. Quantitative sections like calculating population growth rates, interpreting graphs of resource depletion, and working through FRQ calculations on topics like NPP (net primary productivity) and carbon cycling trip up many students. Additionally, the breadth of content—spanning from soil science and water quality to atmospheric chemistry and climate systems—requires strong organizational skills to avoid mixing up concepts across units.
While APES isn't as math-heavy as AP Physics or Calculus, you'll need comfort with algebra, percentages, and basic statistics to handle quantitative questions on the exam. Common calculations include growth rate formulas, dilution problems for water quality, energy transfer percentages between trophic levels, and interpreting data sets about climate or pollution trends. A tutor can help you build confidence with these specific math applications in environmental contexts, so you're not learning math in isolation but seeing exactly how it applies to real-world environmental problems.
The three FRQs on the APES exam require you to integrate multiple concepts, show your reasoning, and often perform calculations—all in limited time. Strong students break down each question systematically: identify what system or process is being tested, list relevant concepts or formulas, and organize your answer to show clear cause-and-effect relationships (e.g., how deforestation impacts carbon cycling and climate). A tutor can teach you to spot question patterns (like "explain why" vs. "calculate and interpret"), practice timing so you don't run out of time on the third FRQ, and learn how to earn partial credit by showing your work clearly even if you're unsure of the final answer.
APES is designed around interconnected systems, so the exam rewards students who see links between units—for example, how population growth (Unit 2) drives resource consumption (Unit 4), which impacts water and air quality (Unit 8), which affects climate (Unit 9). A tutor can help you create concept maps or study guides that show these relationships, practice FRQs that intentionally blend multiple units, and develop a mental framework where you think "if this changes in the biotic community, what happens to nutrient cycling?" rather than treating each unit as isolated. This approach not only improves exam performance but makes the material feel more coherent and easier to retain.
Data interpretation questions test whether you understand what a graph actually shows—not just whether you can read coordinates. For example, a graph showing atmospheric CO₂ levels over time isn't just about the trend; you need to explain the mechanisms behind it (industrial revolution, fossil fuel combustion, reduced carbon sinks). A tutor can teach you a systematic approach: identify the variables and units, describe the trend, explain the mechanism using APES concepts, and connect it to broader environmental impacts. Practice with real exam graphs—like ice core data, population pyramids, or energy flow diagrams—so you're comfortable with the specific types of visualizations the AP exam uses.
The APES exam has 80 multiple-choice questions (90 minutes) and 3 free-response questions (90 minutes). For the MC section, you need to average about 1 minute per question while reading carefully—rushing leads to misreading what a question actually asks. For FRQs, allocate roughly 25-30 minutes per question, leaving 5-10 minutes to review. A tutor can help you practice full-length exams under timed conditions to identify where you lose time (Do you over-explain? Struggle with calculations? Get stuck on unfamiliar graph types?), then build strategies specific to your pace. Mock exams also help you discover which units or question types need more review before test day.
Take a full-length practice test early in your preparation and score it by unit—this shows you exactly which topics (like soil formation, ocean acidification, or energy calculations) are dragging down your score. Many students assume they're weak at "math" when really they struggle with specific applications like NPP calculations or interpreting population growth curves. A tutor can review your practice test results with you, help you understand not just what you got wrong but why (Did you misunderstand the concept? Misread the question? Make a calculation error?), and create a targeted study plan that focuses your limited time on the highest-impact areas rather than reviewing topics you already know well.
APES anxiety often stems from the exam's breadth—nine units covering everything from soil to climate—which can feel overwhelming. Building confidence comes from repeated exposure: taking practice tests, reviewing real exam questions, and getting comfortable with the specific question formats (MC, FRQ, data interpretation) so nothing surprises you on test day. A tutor can help you develop a study schedule that spaces out review over weeks rather than cramming, celebrate progress by tracking score improvements on practice tests, and teach you test-day strategies like starting with your strongest unit to build momentum. Knowing you've practiced with real exam materials and can explain your reasoning clearly—even on tough questions—naturally reduces anxiety.
