Liz
Pre-Algebra Tutor • +41 Subjects
I am a graduate of Washington University in St Louis, where I received my Bachelor of Arts in History with minors in Humanities and Anthropology. Since graduation, I have worked as a tutor, teacher, and director of tutors at a charter public middle school in Boston. During this time I also received my Masters in Mild to Moderate Disabilities from Simmons College. I have worked extensively with students with a range of abilities, including students with specific learning disabilities, emotional impairments, dyslexia, and ADHD. My teaching experience has given me a deep understanding of the knowledge and habits essential to academic success and has given me the opportunity to hone a variety of strategies that ensure students at each level can achieve their academic goals. While I tutor a broad range of subjects, my favorite ones are Reading, Elementary/Middle School Math, History, and Test Prep. In my experience, tutoring is the most rewarding when a student has that "aha!" moment and achieves a new level of understanding and confidence in his/her abilities. I am a firm believer in the transformative power of education, and I see my role to be that of a facilitator and coach who is there to help the student reach his/her goals through individualized support and rigorous practice. In my free time, I enjoy reading, running, practicing my Spanish, and discovering new music. I am also an avid traveler and just got back from a 3 month trip to South America. I look forward to the opportunity to work with you!

AP Calculus BC Tutor • +48 Subjects
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 • +32 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.
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
James
AP Calculus AB Tutor • +41 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.

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.
Sabira
Middle School Math Tutor • +35 Subjects
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

Frequently Asked Questions
10th graders typically find object-oriented programming concepts—particularly inheritance, polymorphism, and encapsulation—most challenging, as these require abstract thinking beyond basic syntax. Many students also struggle with algorithmic thinking and tracing code execution, especially when loops and conditionals are nested. Array and ArrayList manipulation, along with understanding the difference between primitive and reference types, are common pain points. A tutor experienced in AP Computer Science can break down these abstract concepts with concrete examples and help students build mental models before diving into complex implementations.
The Free Response section requires you to write complete methods and classes from scratch, which is very different from multiple-choice. The key is practicing time management—you typically have about 45 minutes for four questions, so spend 2-3 minutes reading and planning before coding. Focus on writing clean, readable code with proper variable names and comments, since partial credit is awarded for correct logic even if your code doesn't compile. Tutors can help you develop a consistent problem-solving framework: understand the requirements, write pseudocode, then implement, which reduces errors and builds confidence under timed conditions.
Effective debugging starts with understanding what your code is actually doing versus what you intended. Use print statements or a debugger to trace variable values at key points in your program—this reveals where logic breaks down. For AP Computer Science specifically, trace through loops step-by-step and verify that array indices are correct, as off-by-one errors are extremely common. A tutor can teach you systematic debugging techniques like isolating sections of code, testing with simple inputs first, and reading error messages carefully rather than guessing at fixes, which saves hours of frustration.
Class design requires thinking about what data an object needs to store (instance variables) and what actions it should perform (methods). Start by identifying the real-world entity you're modeling—for example, a Student class should have variables like name and GPA, and methods like calculateGPA() or updateGrade(). A common mistake is making everything public or static when it should be private, or including methods that don't logically belong to the class. Tutors can guide you through design patterns and help you practice breaking problems into well-organized classes, which is essential for the Free Response section where you're often asked to design and implement your own classes.
The exam tests whether you understand that different algorithms solve the same problem with different levels of efficiency—measured by time and space complexity. For example, a linear search through an array is O(n), while binary search is O(log n), making it much faster for large datasets. You don't need to formally prove Big O notation on the exam, but you should be able to count operations and explain why one approach is better than another. Tutors help students recognize common patterns like nested loops (usually O(n²)) and practice analyzing real code snippets, which appears frequently in both multiple-choice and Free Response questions.
The exam is 3 hours total: 90 minutes for 40 multiple-choice questions (about 2 minutes each) and 90 minutes for 4 Free Response questions (about 20-25 minutes each). Many students spend too long on difficult multiple-choice questions and run out of time for Free Response, where you can earn more points. The strategy is to move through multiple-choice at a steady pace, skip truly difficult questions, and save Free Response for when you're fresh. Practice with full-length timed exams is critical—tutors can help you identify which question types slow you down and develop strategies to work through them more efficiently without sacrificing accuracy.
Syntax errors are frustrating but preventable with consistent habits: use an IDE with syntax highlighting and error detection, develop a checklist (closing all brackets, semicolons, proper method signatures), and proofread before submitting. Many 10th graders rush through code and miss simple mistakes like forgetting a closing brace or mismatching parentheses. The best approach is writing code slowly and deliberately, then testing small sections as you go rather than writing everything and debugging later. A tutor can help you establish good coding practices and teach you to read error messages carefully—they often pinpoint exactly where the problem is, which saves debugging time.
Most students benefit from taking 4-6 full-length practice exams spread across their preparation, starting about 2-3 months before the AP exam in May. Taking them too early (before covering all content) is discouraging; taking them too late leaves no time to address weak areas. After each practice test, analyze which topics or question types caused errors—this identifies exactly what to focus on. Tutors can help you interpret practice test results, create a targeted study plan based on your performance gaps, and take timed practice tests with feedback, which is far more effective than practicing problems in isolation.
