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!

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.

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!
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
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

Frequently Asked Questions
Taking AP Statistics in 9th grade is less common than taking it in 10th or 11th grade, but it's increasingly popular for mathematically advanced students. Since AP Statistics doesn't require calculus as a prerequisite (unlike AP Calculus), strong algebra and data reasoning skills are often sufficient. However, the course moves quickly and covers probability, distributions, and inference concepts that many 9th graders find conceptually challenging, which is why early tutoring support can be particularly valuable for building confidence and preventing gaps.
9th graders typically struggle most with probability concepts (especially conditional probability and independence), understanding sampling distributions, and interpreting confidence intervals and hypothesis tests. Many students also find the transition from descriptive statistics (graphs and summaries) to inferential statistics conceptually difficult—it requires thinking about populations they can't see and understanding why sample data can tell us about larger groups. Additionally, the interpretation of p-values and statistical significance is often misunderstood, leading to errors on both multiple-choice and free-response sections.
AP Statistics is unique among AP math courses because students receive a formula sheet during the exam—memorization is far less critical than understanding when and how to use formulas. Instead, 9th graders should focus on conceptual understanding: knowing why a t-test is appropriate in one situation but a z-test in another, or recognizing when data violates assumptions for a particular procedure. Tutors typically emphasize building this decision-making framework rather than rote memorization, which helps students tackle unfamiliar problems on the exam.
Calculator skills are essential in AP Statistics—students are expected to use graphing calculators (like TI-83/84) to compute summary statistics, create plots, and run statistical tests quickly and accurately. Many 9th graders haven't developed these skills yet, and fumbling with calculator syntax during the exam wastes precious time. A tutor can accelerate calculator proficiency by teaching efficient keystrokes for normal distributions, t-tests, linear regression, and chi-square tests, allowing students to focus mental energy on interpreting results rather than mechanics.
The free-response section requires students to not only perform calculations but also communicate their reasoning clearly—graders want to see that you understand what you're doing, not just the final answer. 9th graders often struggle to explain their choice of procedure, interpret results in context, or identify limitations in their analysis. Tutoring focused on free-response practice helps students learn to structure answers (stating the procedure, checking conditions, showing work, and interpreting findings in plain language), which significantly improves scores on this section.
The AP Statistics exam has 40 multiple-choice questions in 90 minutes (roughly 2 minutes each) followed by 6 free-response questions in 90 minutes. Many 9th graders underestimate how quickly they need to work on the multiple-choice section and run out of time on free-response, where they can earn more points. Tutors help students develop a pacing strategy: practicing timed sections regularly, learning to skip difficult multiple-choice questions and return to them, and allocating roughly 15 minutes per free-response question to allow time for checking work.
Most students benefit from completing 4-6 full-length practice tests under timed conditions in the weeks leading up to the exam, but the quality of practice matters more than quantity. After each test, reviewing mistakes and understanding why wrong answers were chosen is critical—this is where tutors add value by helping students identify patterns in their errors (Are you misinterpreting p-values? Forgetting to check conditions? Misreading questions?). For 9th graders, starting practice tests earlier in the year and spacing them out allows time to address weak areas before the exam.
Score improvement depends on where a student starts and how consistently they engage with tutoring. A student scoring in the 2-3 range (below proficient) often sees the most dramatic gains—moving to a 4 or 5—because tutoring addresses fundamental conceptual gaps and test-taking strategies. Students already scoring 4s may improve more modestly because they've mastered core concepts; tutoring then focuses on precision, free-response communication, and avoiding careless errors. Consistent tutoring (weekly sessions for several months) combined with regular practice testing typically yields 1-2 point improvements on the 1-5 scale.
