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

I am a published author who has enjoyed “coaching” our daughter, as she navigated through high school, college and graduate school. I mentor college juniors who are seeking careers in financial services, and I serve as a peer resource to professionals who are transitioning from private industry to the nonprofit sector. Hobbies: reading, cooking, writing, books, music, art, travel
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 algorithmic thinking and translating logic into code syntax. Concepts like loops, conditionals, and functions require understanding both the abstract logic and the specific programming language rules. Additionally, many 9th graders find object-oriented programming (classes and objects) conceptually difficult since it requires thinking about code structure differently than procedural programming. A tutor can break these down into smaller, digestible pieces and provide hands-on practice with real code examples.
Debugging is a critical skill that separates students who struggle from those who excel in AP Computer Science. A tutor can teach systematic approaches like using print statements strategically, understanding error messages, and tracing code execution step-by-step. They'll help you develop the habit of reading error messages carefully rather than guessing fixes, and show you how to isolate problems by testing small code segments independently. With guided practice, debugging becomes a logical process rather than a frustrating guessing game.
Many 9th graders get caught up memorizing syntax rules and lose sight of the underlying logic—or vice versa. A tutor focuses on teaching logic first through pseudocode and flowcharts, then introduces the specific syntax needed to express that logic in your programming language. This approach means you're not just copying code patterns; you understand why each line exists. Once the logic is solid, syntax becomes a tool to express your ideas rather than a barrier to learning.
Larger projects intimidate students because they seem overwhelming as a whole. A tutor teaches you to break projects into smaller, manageable components—start with the core logic, test it thoroughly, then add features incrementally. They'll help you plan your approach before coding, identify which parts are most challenging, and know when to refactor code to avoid getting stuck. Learning to work on projects methodically rather than trying to build everything at once dramatically reduces frustration and improves code quality.
Variable scope—understanding where a variable exists and can be accessed—is abstract and causes confusion for many 9th graders because it's invisible in the code. A tutor uses visual diagrams and tracing exercises to make scope concrete, showing exactly which parts of your code can 'see' which variables. They'll have you practice identifying scope errors before running code, which builds intuition. Once you can predict scope issues, you'll catch a whole category of bugs that otherwise seem mysterious.
Strong AP Computer Science students think about test cases while writing code, not after. A tutor teaches you to identify edge cases and boundary conditions early—what happens with empty inputs, negative numbers, or maximum values? They'll show you how to write simple test cases first, then build code to pass them. This approach catches bugs early and gives you confidence that your solution actually works. It's a professional programming practice that transforms how you approach every assignment.
Many AP Computer Science courses include pair programming or code reviews, which require communicating about code clearly—a skill separate from writing code itself. A tutor can help you articulate your logic, explain your design choices, and give constructive feedback on others' code. These skills matter because they help you learn from different approaches and prepare you for real-world programming environments. Tutoring can include mock code reviews where you practice explaining your thinking and receiving feedback productively.
While 9th graders should focus primarily on correctness and clarity, understanding that some solutions are more efficient than others is important. A tutor introduces efficiency concepts gradually—showing why nested loops might be slower than alternatives, or how certain data structures make operations faster. You don't need to memorize Big O notation early, but recognizing that your code's approach matters helps you write better solutions. As you progress, efficiency thinking becomes second nature and crucial for handling larger datasets.
