Award-Winning AP Computer Science Tutors

Christina's CS degree means she's written enough Java to know exactly where AP Computer Science A gets tricky — the leap from writing simple methods to designing full classes with inheritance, or the moment recursion stops feeling like magic and starts making sense. She teaches students to trace through code systematically, building the kind of debugging instinct that pays off on both multiple-choice and free-response sections.

Double-majoring in computer science and English gives Milan an unusual edge when it comes to AP Computer Science A — he writes Java with technical precision but also explains it in plain language, which matters when students are stuck on why a recursive call unwinds the way it does or how inheritance actually changes method behavior. His CS coursework means topics like array traversal, class design, and algorithm tracing are daily practice, not distant exam material.

Most AP Computer Science A students get tripped up not on syntax but on thinking through what their code actually does — tracing a loop iteration by iteration or figuring out why a method returns the wrong value. Dennis teaches across Java, JavaScript, and web development, which means he can explain object-oriented concepts from multiple angles and show students how the same logical patterns appear across languages. Rated 5.0 by students.

I'm a recent graduate of the California Institute of Technology in Economics and Computer Science. I was also accepted at Harvard, Princeton, MIT, and Stanford. I have a broad range of interests spanning science, math, engineering, social science, the humanities, the arts, and athletics (I also played on the Caltech basketball team). My background allows me to tutor general college prep, especially the SAT, ACT and the GRE. I love to teach analytical thinking, ranging from advanced Math and Physics to strategies for understanding literature and developing arguments.

I'm currently majoring in bioengineering/pre-med at Rice University. I graduated as the valedictorian of my high school class. My interests include biology, math, and violin performance. I've done neuroscience research at the Jungers Center for Neuroscience Reseach and the Oregon National Primate Research Center. I've also done molecular biology research at the Oregon Stem Cell Center.

The AP Computer Science exam tests both conceptual understanding and the ability to trace through code under time pressure — two skills that require different preparation strategies. Sam's electrical and computer engineering background means he can walk students through recursion, object-oriented design, and array manipulation with the kind of precision that turns confusing exam questions into recognizable patterns.

As experienced and passionated educator with a Bachelor's degree in Computer Science from Rice University, I am passionate about empowering students to achieve their academic goals. With over 3 years of tutoring experience in subjects such as AP Computer Science A, Machine Learning, and SAT Math, I adapt to different learning styles and create a supportive learning environment. My teaching philosophy centers on personalized instruction, where I connect with each student to understand their unique learning styles and challenges. I take pride in guiding students through the complexities of computer science and college application essays, equipping them with the skills they need for future success. Outside of tutoring, I enjoy exploring new technologies and engaging in coding projects to improve my teaching approach.

I am a rising senior at Duke University. I major in Computer Science and am also getting a minor in Physics. I have had experience tutoring/teaching as a teaching assistant for three classes: Intro to Databases, Electricity and Magnetism (for engineers), and Computer Network Architecture. I have had industry experience in software development as an intern for IBM and a cybersecurity analyst for TIAA. Outside of school/work, I play the piano and train with the Duke Taekwondo Club. I have a strong background in computer science, physics, and math, but I love learning about and helping students with a wide variety of subjects!

Kevin earned his master's in computer science from NYU, so the Java fundamentals tested in AP Computer Science A — class design, control flow, recursion — are concepts he's built on for years rather than topics he's revisiting. He's the kind of tutor who'd rather over-explain a tricky loop trace than leave any ambiguity, which pays off when students hit the free-response section and need to write clean, correct code under pressure. Rated 4.8 by students.

I'm a freshman at Stanford University pursuing a degree in mathematical and computational science. I've been tutoring students from grades 3-12 throughout high school, and I look forward to continue in college. Nothing excites me more than learning something new, and I strive to share my excitement with my tutees.

Brian owns a web design business alongside his CS studies at Case Western Reserve, so he's not just learning Java in a classroom — he's shipping real code and debugging real problems on a regular basis. That practical loop of building, breaking, and fixing software gives him a concrete way to teach AP Computer Science A topics like object-oriented design and algorithm tracing through actual examples rather than abstract diagrams. Rated 5.0 by students.

As a lab assistant and grader for Rice University's Fundamentals of Computer Engineering course, Omar has seen firsthand where students stumble on AP Computer Science topics like recursion, array manipulation, and object-oriented design. He breaks down each concept by connecting it to how computers actually execute code at the hardware level — a perspective most AP prep can't offer. Rated 5.0 by students.

Studying Computer Science at Cornell gives Jonathan daily exposure to the data structures, object-oriented design, and algorithmic thinking that drive the AP Computer Science exam. He breaks down topics like recursion and sorting algorithms by connecting them to real engineering problems from his coursework, making abstract concepts click faster.

I am really passionate about all the subjects that I teach and my goal with tutoring is to inspire my students to feel the same passion. I love tutoring because I love being able to make a positive difference in my students lives.

I am a Stanford student from Maryland studying Political Science and Computer Science. I graduated from high school in 2015, where I was active as the captain of my high school sailing team, a section leader in the orchestra, and part of the STEM magnet program Project Lead the Way. I am currently taking some time off from school to be around family here in Massachusetts and while I will be taking a few classes, I have plenty of time and lots of flexibility. I am excited to work with middle and high school students in math, reading and writing, social studies, and computer science. In addition to taking classes and tutoring this fall I will be volunteering in after school programs with low income middle and elementary school students.

Columbia's CS program has Julian writing Java and working with object-oriented design patterns well beyond the AP level, which means he can zoom in on exactly the pieces — like loop tracing, array logic, or class construction — that the exam actually tests. He's spent enough time in group study sessions watching classmates struggle with gaps in foundational concepts to know that solid understanding of how each line of code executes matters more than memorizing syntax.
