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.

Currently studying computer science at MIT, Brice writes Java and Python regularly enough that AP Computer Science A topics like inheritance, polymorphism, and recursive methods feel like second nature rather than exam abstractions. He teaches the *why* behind each design pattern — why you'd use an ArrayList over an array, why a method should return a value instead of printing it — so students build real programming intuition. Rated 4.9 by students.

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!

Recursion, sorting algorithms, and object-oriented design aren't just AP exam topics for Sebastian — they're concepts he uses daily in his computer science coursework at UCF. He teaches students to trace through code by hand before running it, building the kind of debugging intuition that turns a 3 into a 5. Free-response questions get special attention since that's where most points are left on the table.

Hackathons and robotics competitions taught June to debug under pressure and think through code systematically — exactly the skills AP Computer Science A tests on free-response questions. Her electrical engineering studies at Brown mean she understands computing from the hardware up, giving her a concrete way to explain why Java handles variables, memory, and control flow the way it does.

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.

I'm a coterminal master's student at Stanford University in California majoring in Computer Science (Biocomputation). Throughout high school and college, I've taken many courses in computer science, the life sciences (biology and chemistry), and math; and I've been through a lot of standardized tests. For computer science in particular, I have a lot of experience writing software in Python and C++ for AI and systems classes, and I'll be interning as a software engineer at Facebook this summer. I got a lot of great tips and mentorship from tutors along the way, and would love to pass along what I know!

While computer science isn't John's primary credential, his engineering training at a program rigorous enough to earn Tau Beta Pi membership gave him strong foundations in algorithmic thinking and problem decomposition. He approaches AP Computer Science concepts like recursion, sorting algorithms, and object-oriented design with the structured logic of an engineer who learned to code as a working tool.

I'm Cindy! I'm a freshman at Harvard University and graduated from San Mateo High School this past year. I love to teach and have years tutoring students of all ages in a variety of subjects. Feel free to send me a message if you have any questions or would like to schedule a tutoring session!

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.

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 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.

I'm Dennis. I study physics, math, and computer science. I have done research about cosmic ray acceleration at supernova shock fronts in the Princeton University Department of Astrophysics, simulating how the turbulent plasmas push protons and ions. I have also worked at the Norfolk State University Department of Engineering, designing, simulating, optimizing, and building light filters for wavelength-division optical-electronic multiplexers. Another field I study is the mathematics of quasicrystals and aperiodic tilings, such as the Penrose tiling of rhombuses.
