Riley

AP Statistics Tutor • +28 Subjects

I primarily tutor a lot of math classes. Anything from elementary school through undergrad. High school Geometry? Yep! Real Analysis? Absolutely! Python? Not quite math, you tricky person, but sign right up. I tutor a bit of physics and computer programming as well. Test prep, too. But who am I? I am a math music philosophy nerd. I love Gauss almost as much as I love Bach and I love Bach almost as much as I like Hegel. So chat to me about that stuff if you are so inclined. But you want to just chill and have homework help? That's quite all right, too!

Mark

AP Statistics Tutor • +27 Subjects

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.

Sruti

Pre-Algebra Tutor • +17 Subjects

I am a PhD student at Carnegie Mellon University in the field of Electrical and Computer Engineering. I recently completed my bachelors also at Carnegie Mellon University in Electrical and Computer Engineering as well as Human Computer Interaction. Over the last several years, I have experience teaching a wide variety of students ranging from elementary school math, introduction to programming for children, as well as college level classes. While I tutor a broad range of subjects, I am most passionate about Math, Physics, and Computer Science. I really enjoy teaching programming, especially in fun and engaging ways. I like to relate what I teach to things my students are passionate about, or teach them through fun activities and games, so that they are easier to understand. I also help students prepare for standardized tests and have several strategies that I can share, especially for the math section of the tests. In my spare time, I enjoy dancing, music, hiking and anything outdoors!

Simon

Probability Tutor • +11 Subjects

I have a PhD in computational physics from the University Of Pennsylvania, as well as a degree in physics and computer science from the University Of British Columbia. I have years of experience as a teaching assistant and have been an instructor at a college level. I've taught hundreds of students to program effectively in a wide range of languages, as well many different physics courses. In the corporate world, I've found the experience of watching a mentee grow and thrive the most satisfying. While small classroom experiences are fun, I love working one on one with students - the moment when an idea "clicks" is just as fun for the teacher as it is for the student!

Benjamin

Applied Mathematics Tutor • +25 Subjects

I received my PhD in mathematics from Drexel University in 2019. I really enjoyed teaching as a graduate student, and working as a tutor here seems like a nice way to get back into it. Before graduate school, I went to Johns Hopkins. I started out as a "chemical and biomolecular engineering" major, but then ended up switching to a double major in math and electrical engineering. I graduated with a BA in math and MS in electrical engineering. From there, I went to Drexel University to write and defend my dissertation in mathematics, which was about two unsolved problems in linear algebra. While in Johns Hopkins and Drexel University, I ended up teaching a lot of math and a bit of science not only as a tutor, but also as a teaching assistant and as a primary instructor. Since then, I've been working as a mathematician; I worked as a postdoctoral researcher in the Free University of Brussels for one year, and then as a research scientist at the Air Force Research Lab in Dayton, Ohio for two years. It's been a rewarding career, but I have missed teaching. When it comes to teaching, I try my best to take a flexible approach and meet students where they are. I am a big believer in the power of intuition and curiosity, so I try to teach in a way that nurtures both. I find that it is important not only to know how to get from problem statement to solution, but also to have some understanding of why the pieces fit together the way they do. Besides math and teaching, I enjoy singing, playing piano, playing online chess, and doing the New York Times crossword (and other word games). Lately, I've been trying to get back into running and yoga.

Frequently Asked Questions

Debugging is as much about developing a systematic mindset as it is about technical skills. A tutor can teach you how to read error messages carefully, use debugging tools effectively (like breakpoints and print statements), and think through your code logically rather than guessing at fixes. They'll also help you understand common error patterns—like off-by-one errors in loops or null pointer exceptions—so you can spot and prevent them faster in future projects.

Syntax is the specific rules of a language (like how to write a for loop in Python vs. Java), while logic is the problem-solving approach behind your code. Many students get stuck memorizing syntax but struggle with algorithmic thinking—breaking down a problem into steps and choosing the right data structures. A tutor helps you focus on building strong logic skills first, which makes learning new languages and syntax much easier, since the core thinking transfers across all programming languages.

Data structures like arrays, linked lists, hash tables, and trees are abstract concepts that are hard to visualize without hands-on practice. Students often memorize definitions without understanding when and why to use each one, leading to inefficient solutions. A tutor can walk you through real coding problems, show you how different structures perform, and help you build intuition for choosing the right tool—turning data structures from abstract theory into practical problem-solving skills.

Code review teaches you to think like a professional developer—considering readability, efficiency, and best practices, not just whether code "works." A tutor can review your projects, point out where variable names are unclear, where you're repeating code unnecessarily, or where a more efficient algorithm would help. This feedback loop is invaluable because you learn to write better code the first time, catch your own mistakes faster, and develop habits that make collaboration easier later.

Building real projects forces you to integrate multiple concepts—maybe combining loops, conditionals, functions, and file I/O in one program—rather than learning them in isolation. A tutor can guide you through project planning, help you break large problems into manageable pieces, and provide feedback as you build. This approach strengthens your ability to think through problems end-to-end and gives you a portfolio of work that demonstrates your skills to colleges or employers.

A tutor can help you explore different areas by working on small projects in each domain and discussing what resonates with you. Web development focuses on front-end and back-end technologies; data science emphasizes statistics and machine learning; game development combines graphics, physics, and real-time problem-solving. Your tutor can help you understand the core skills each path requires and guide you toward specialization based on your interests and career goals.

Algorithmic thinking means breaking a problem into precise, step-by-step instructions before you write any code—thinking about efficiency, edge cases, and the order of operations. It's hard because it requires abstract reasoning and practice; many beginners jump straight to coding without planning. A tutor helps you develop this skill by working through problems on paper first, discussing different approaches, and analyzing why one solution is better than another—building the foundation for tackling complex problems independently.

Error messages are written for computers and experienced programmers, so they often feel cryptic to beginners—a stack trace showing five nested function calls can be overwhelming. A tutor teaches you to focus on the most relevant line, understand what the error type means (like IndexError vs. TypeError), and trace backward through your code to find the root cause. Over time, you'll recognize patterns and develop the skill to use error messages as debugging guides rather than sources of frustration.
