Award-Winning AP Computer Science Tutors
serving Appleton, WI

Between physics problem sets and computer science coursework at Cornell, Joel writes Java and Python to solve real computational problems — not just classroom exercises. That dual perspective is especially useful for AP Computer Science A topics like algorithm design and object-oriented programming, where understanding the logic behind the code matters as much as getting it to compile. His 35 ACT reflects the kind of precise, systematic thinking that translates directly to tracing through free-response questions.

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.

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.

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 sophomore at Vanderbilt University studying computer science, currently focusing on iOS and game development. I like growing as a person, but I find it much more interesting and rewarding to grow other people. Seeing a student change, not in intellect but in perspective, is fascinating. I like to focus more on concepts rather than memorization so that students will have the tools to excel in any facet of academia, beyond some random test that holds too much significance.

The AP Computer Science A exam leans heavily on array manipulation, recursive methods, and class design — topics that reward structured thinking over memorization. Lloyd's data science background at Rochester means he tackles these concepts daily, and he teaches students to trace through code by hand so they can predict output on free-response questions without second-guessing.

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.

Jett codes in Java, Python, and C as part of his electrical and computer engineering program at UT Austin, so the AP Computer Science A curriculum — from writing classes to implementing algorithms — overlaps with work he's already doing for his degree. Where he especially shines is connecting programming logic to the underlying hardware, explaining how a for-loop or recursive call actually executes at the machine level, which makes debugging and tracing problems far less mysterious. Rated 5.0 by 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.

I am a graduate of Stanford University, where I received a BS in Cognitive Science and an MS in Computer Science. After graduation, I spent a summer in Palestine, where I taught web development, app development, and entrepreneurship to a cohort of overenthusiastic high school students; now, I've moved halfway across the country from the Bay Area to the Twin Cities. From volunteering with organizations like Twin Cities Rise and The Mid-Continent Oceanographic Institute to checking out art institutions like the Walker and Mia, it's been such a wonderful time settling into this new place that I call home.

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 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!

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.
