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!
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

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!

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.

Frequently Asked Questions
Students typically struggle most with object-oriented programming concepts—particularly inheritance, polymorphism, and encapsulation—since they require thinking about code structure abstractly. Array and ArrayList manipulation also trips up many students, especially when working with 2D arrays or nested loops. The free response section (which makes up 40% of the exam) demands strong problem-solving skills and the ability to write clean, efficient code under time pressure, which is where many students first realize they need targeted help.
The exam is split into two sections: a 90-minute multiple-choice section (40 questions) and a 90-minute free response section (4 coding problems). The multiple-choice tests conceptual understanding and code tracing, while free response requires writing actual code to solve problems. Many students underestimate the free response section—it's not just about getting the right answer, but writing readable, well-structured code that the graders can follow. Tutors often focus heavily on free response practice because that's where students can make the biggest score gains.
Code tracing appears throughout the multiple-choice section and is essential for understanding what code actually does versus what you think it should do. Many students skip this step and rely on intuition, which leads to careless mistakes. Effective practice involves working through code line-by-line, tracking variable values, and predicting output before running the code. A tutor can help you develop systematic tracing habits and identify common patterns (like off-by-one errors in loops) that appear repeatedly on the exam.
The key is to break each problem into smaller, manageable parts rather than trying to write the entire solution at once. Start by identifying what data structures you'll need, write helper methods first, and test your logic with simple examples before handling edge cases. Time management is critical—you have roughly 22 minutes per problem, so practicing under timed conditions is essential. Many students benefit from learning a consistent template for approaching different problem types (searching, sorting, 2D arrays, etc.) so they don't waste time deciding how to structure their code.
These concepts are abstract, so they require moving beyond memorizing definitions to actually seeing them in action. Start by understanding that inheritance lets you reuse code by creating parent-child class relationships, while polymorphism lets you use a parent class reference to call child class methods. The exam often tests whether you can predict which method will execute in a polymorphic situation—this requires tracing through class hierarchies carefully. Working through progressively complex examples with a tutor, from simple parent-child relationships to multi-level inheritance, helps solidify when and why to use these tools.
Ideally, start taking full practice tests 4-6 weeks before the exam so you can identify weak areas early. Take at least 3-4 complete, timed practice tests under exam conditions—this builds stamina and reveals your pacing issues. After each test, spend time analyzing wrong answers: Did you misread the question? Trace code incorrectly? Run out of time? This diagnostic work is more valuable than taking more tests. A tutor can help you analyze practice test results strategically and focus your remaining study time on the specific concepts and question types where you're losing points.
Debugging is critical because the free response section requires writing code that actually works—partial credit is limited if your logic is fundamentally flawed. Students who develop strong debugging habits can catch their own mistakes during the exam, which saves time and points. The exam doesn't explicitly test debugging, but students who can systematically identify why code isn't working as expected write better solutions faster. Learning to use print statements strategically, test edge cases, and think through your code before writing it are habits that distinguish students scoring 4s and 5s from those scoring 2s and 3s.
Look for someone who has recent experience with the AP Computer Science A curriculum and can explain both the 'what' and the 'why' behind concepts like inheritance and polymorphism. They should be comfortable live-coding and walking through free response problems under timed conditions, since that's where you'll gain the most confidence. Strong tutors also help you develop a personal study strategy based on your specific weak areas—whether that's code tracing speed, free response time management, or conceptual understanding of certain topics. Ask about their experience with exam grading rubrics, since knowing exactly what graders are looking for in free response answers directly impacts your score.
