I'm a college student at Saint Vincent College in Latrobe, Pennsylvania. I am in my junior year of a computer science degree. Outside of classes, I work as a college tour guide, IT technician, and camp counselor. I love working with young people to plan for and achieve success, especially as it pertains to test and college prep. I have been working with young people from an early age, at summer camps, church groups, and as a part of my college's admissions department. I am ready to adapt to every student's unique learning styles and habits, and I hope to see my work inspire a boost in performance and confidence for many.

I am a graduate from Rochester Institute of Technology with a master's in Game Design and Development. My passions lie in everything related to games and mathematics. In the past, I have tutored various subjects in mathematics throughout high school and college, including but not limited to Algebra, Algebra II, Trigonometry, Calculus, Discrete Mathematics, Mathematics of Graphical Simulation, and Linear Algebra. As for technology, I am more than happy to reach out for help in Web Development (HTML, CSS, Javascript) or C# programming. I believe that every person can learn any topic. While every individual has different tastes, strengths, and weaknesses, there is no such thing as an "incapability" to know a subject. Education often possesses a guise of anti-fun, but I can promise you that all topics can be engaging, and I am willing to show you how engaging mathematics and technology can be. As a Game Designer, I have a deep interest in both playing games and making games. This includes games of all kinds: video games, board games, tabletop role-playing games, trading card games, miniatures, and even some sports like tennis or ping pong. Games act as a fantastic teaching tool. They teach by design without users recognizing. It is always a satisfying moment when somebody says "I learned that word from Magic" or "D&D taught me that." Remember: you can succeed. If something is important to you, then it's always worthwhile.

Triple-majoring in Computer Science, Mathematics, and Economics at IUPUI means Darren lives in Java and algorithmic thinking daily — not just for one class, but across disciplines that each demand rigorous logic and clean code. That cross-disciplinary perspective is especially useful for AP Computer Science A's free-response questions, where breaking a problem into smaller computational steps mirrors the same decomposition skills his math and econ coursework reinforces every week.

AP Computer Science isn't listed among Hannah's core subjects, but her physics degree required writing code to model systems, analyze data, and solve computational problems — skills that map directly onto the algorithmic thinking and logical reasoning the AP exam tests. She's strongest at teaching students to slow down and trace through control flow and conditionals methodically, the same systematic approach her physics training drilled into her.

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.

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.

Scoring a 5 on the AP Computer Science exam while simultaneously deep in calculus, biology, and chemistry APs gave William a clear picture of how CS thinking differs from other STEM disciplines — it's less about formulas and more about structuring logic step by step. His dual engineering track at Vanderbilt (biomedical and chemical) means he regularly writes code to process lab data and model systems, keeping Java concepts like iteration, array handling, and method design sharp through actual use rather than exam review alone.

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.

Studying computer science while double-majoring in studio art gives Parker an unusual edge when teaching AP Computer Science — he thinks visually about code structure, sketching out class hierarchies and loop logic as diagrams before translating them into Java. That creative problem-solving approach, paired with daily coursework in algorithms and data structures, means students get explanations tailored to how they actually think rather than a one-size-fits-all walkthrough. Rated 5.0 by 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.

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.

Two years writing computerized tasks for Ohio State's Clinical Neuroscience Laboratory gave Luke hands-on experience building software to solve real research problems — the kind of structured, logical coding that maps directly onto AP Computer Science A topics like control flow, method design, and class construction. His psychology training also sharpens how he explains tricky concepts, since he's attuned to where confusion actually originates rather than just what the correct answer looks like. Rated 4.8 by students.
