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

I am an aspiring applied mathematician, with particular interest in image processing and climate science. I graduated in May 2017 from Washington University in St. Louis with a bachelor's in physics and mathematics, and am beginning a PhD program in September 2017 at the University of Chicago in Computational and Applied Mathematics. I've tutored introductory physics students for three years and enjoyed it thoroughly, as a chance to help other students while revisiting fundamental concepts to enhance my own knowledge. I'm eager to continue reaching out and helping students of math and physics to succeed and, furthermore, to appreciate the beauty and power of these subjects.
Elena
Calculus Tutor • +31 Subjects
I am a graduate of McGill University (BA First Class Honors) and the University of Edinburgh (MSc First Class Honors with Distinction) with over eight years of tutoring experience. I am currently a curriculum developer for a company which creates relatable and culturally-literate courses for middle and high-schools, and am particularly adept at communicating and explaining concepts in a quirky, engaging, and intelligent manner. I was named Scotland International Young Thinker of the Year 2014 for exactly that sort of work. Much of my tutoring background is in test-prep and essay coaching, which I enjoy because it allows the tutor and student to think strategically together, and work as a team to achieve concrete results. I have worked with students ranging in age from 6-32, and believe that, in an educational context, a few jokes never hurt anybody. I love reading and learning, and my educational approach is centered around making the material just as engaging to students as it is to me. I think J.K. Rowlings, the writer of Harry Potter, is just as brilliant as Stephen Hawking, and in my free time, I manage my (terrible) fantasy baseball team, write songs for my comedy band, and crack jokes about terrible science-fiction movies with my friends.

I am currently attending Johns Hopkins University, pursuing a dual degree in Computer Science and Applied Math and Statistics. I love helping students and I love the feeling I get knowing that I was able to use my knowledge to make someone else happier. My favorite subject to teach is math because there are so many ways to learn it and if one way does not help I can use another. I used to teach taekwondo and interacted with all kinds of students, and I'm excited to help out more! Hobbies: books, reading, music, writing, art
James
AP Calculus AB Tutor • +40 Subjects
I am currently a senior at Harvard College where I study chemistry, and I'll be attending Columbia Medical School next year. I have years of experience tutoring college students in math (mostly calculus) and chemistry including both general and organic chemistry. In addition, I am very familiar with all sections of the SAT and ACT having prepared several high school students for these tests. I believe that every student is capable of boosting his or her baseline score on these tests, so long as he or she works hard to get to know the format of the tests and the most popular types of questions. I tutor because I love seeing students develop a genuine passion for the subjects they once disliked (such as math and science), once they understand the power of these subjects and their applications to the real world.

Isabella
Pre-Algebra Tutor • +27 Subjects
I am a graduate of MIT. I received my Bachelor of Science in Mathematics with minors in Management Science and Ancient and Medieval Studies. Since graduation, I have started my PhD at Georgia Tech in Operations Research. Throughout my career I have TA'd several math and computer science courses at the college level. I have also taught at summer programs for gifted middle school and high school students. I am passionate about tutoring kids in math and science because I think that a strong foundation in STEM at an early age can set the tone for their future. In my spare time I like to engage in athletics, and was a Division 1 rower in college. Hobbies: reading, swimming, writing, books, music, running, art

Justin
Calculus Tutor • +38 Subjects
I am a graduate of the University of Chicago where I received my Bachelor of Arts in Philosophy. Currently, I am in the master's program at the University of New Mexico where I am continuing my education in philosophy. Ultimately, I hope to go on to earn a PhD in Philosophy so that I can continue engaging in my passions for learning and teaching. While in school, I have spent countless hours coaching high school speech and debate both in person and working online with students across the country. My focus in coaching has been to emphasize philosophy and critical thought to prepare students to think through novel arguments on their own. I am passionate about teaching and tutoring because I love seeing students learn to be intellectually independent and think through problems on their own terms by developing their critical thinking skills. I have devoted my life to education because I am passionate about it, and I try to share some of my passion for learning with the students I work with. I tutor all sorts of Standardized Tests, and I particularly enjoy working on logic-based problems like analogies and math sections. When I am not tutoring or reading for school, I enjoy strategy games (both board games and video games), listening to music, hiking, playing basketball, and just relaxing with friends.

Frequently Asked Questions
Students typically find conditional probability, Bayes' theorem, and moment-generating functions (MGFs) most difficult on Exam P. Many struggle with translating word problems into proper probability notation and identifying when to use different probability distributions (binomial, Poisson, normal, exponential, etc.). Additionally, multivariate distributions and the relationship between joint, marginal, and conditional distributions often trip up test-takers who haven't developed strong intuition for how these concepts connect. Personalized tutoring helps by breaking down these abstract concepts with targeted practice on the specific problem types that appear on the exam.
Exam P requires solid calculus skills, particularly integration, differentiation, and working with limits—these are essential for deriving probabilities from probability density functions (PDFs) and cumulative distribution functions (CDFs). You should also be comfortable with algebra, summation notation, and basic combinatorics (permutations and combinations). Many test-takers underestimate how much calculus appears on Exam P; if your calculus is rusty, a tutor can help you refresh those skills alongside probability concepts so you're not held back during exam prep.
Most candidates spend 100-150 hours preparing for Exam P, though this varies based on your math background and starting point. With personalized tutoring, you can compress this timeline by focusing intensively on your weak areas rather than reviewing material you already know. A typical tutoring plan involves 2-4 sessions per week over 3-4 months, combined with independent problem-solving between sessions. Your tutor can assess your current level and create a customized study schedule that targets the specific topics where you need the most help.
An excellent Exam P tutor should have passed the exam themselves and ideally hold an actuarial credential (ASA, FSA, or equivalent), which demonstrates deep mastery of probability theory and its applications. They should be able to explain not just how to solve problems, but why certain probability techniques apply in specific situations—this conceptual understanding is crucial since Exam P tests both computational skills and theoretical knowledge. Look for tutors who can identify your specific misconceptions (like confusing independence with mutual exclusivity) and have experience teaching the exam's most notoriously difficult topics like MGFs and multivariate distributions.
Exam P word problems are deliberately written to test whether you can identify the underlying probability structure rather than just recognize a familiar problem type. A question might describe a real-world scenario (insurance claims, equipment failures, customer arrivals) without explicitly telling you it's a Poisson process or exponential distribution—you have to recognize the pattern. Many students struggle because they've memorized formulas but haven't developed the intuition to match problem descriptions to the right distribution. Tutoring helps by walking you through the problem-solving framework: identifying what random variable you're modeling, determining its distribution, and then selecting the appropriate formula or technique.
MGFs are one of the most abstract topics on Exam P, and many students treat them as a black box. The key is understanding that an MGF is a tool for extracting moments (mean, variance, higher moments) from a distribution—it's not just a formula to plug into. A tutor can help you see why MGFs matter: they make it easier to find the distribution of sums of random variables, they help prove that two distributions are identical, and they reveal properties of a distribution that aren't obvious from the PDF alone. Working through derivations of MGFs for common distributions (exponential, normal, Poisson) and seeing how to use them to find means and variances builds the intuition that memorization alone can't provide.
Effective Exam P practice involves more than just solving problems repeatedly—it requires deliberate, targeted work on your specific weak areas. Start by identifying which topics consistently trip you up (through diagnostic quizzes or tutoring sessions), then focus intense practice on those areas before moving to mixed problem sets. Use the official SOA sample questions and past exams as your primary practice source, since they reflect the actual exam's difficulty and style. A tutor can help you analyze your mistakes to identify patterns: Are you misidentifying which distribution to use? Making integration errors? Misunderstanding conditional probability? This diagnostic approach is far more efficient than grinding through hundreds of generic practice problems.
Multivariate distributions require you to juggle joint PDFs, marginal distributions, conditional distributions, and independence simultaneously—it's easy to get lost in the notation and lose sight of what you're actually calculating. A tutor can break this down systematically: starting with simple two-variable problems, building your intuition for how marginalizing works (integrating out one variable), then showing how conditional distributions follow from the definition P(X|Y) = f(X,Y)/f(Y). They can also help you recognize which Exam P problems are testing your understanding of these relationships versus which are just computational exercises. With guided practice on increasingly complex problems, multivariate distributions shift from feeling abstract to feeling like a natural extension of single-variable probability.
