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
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.
