Matthew
Pre-Algebra Tutor • +39 Subjects
I'm a highly creative person who works best with visual thinkers. Very recently graduated from Stanford University, I majored in Human Biology with a concentration in Bioinformatics and Stem Cell Science. Technical though my background may be, I am currently gigging as a singer/songwriter/composer in NYC and tackle even the most hard-science of problems with a top-down, big-picture, holistic approach. If you have a propensity to look at problems in a cross- or inter-disciplinary manner (or want to learn how to do so), I'm the tutor for you!
Charles
AP Calculus AB Tutor • +25 Subjects
I am a junior Mechanical Engineering major at Yale, and I hope to become a Naval Aviator after college. I am also a varsity sailor, and enjoy playing music with friends when I can get some free time. I have been tutoring my fellow students throughout my entire academic career, and I would best describe my tutoring style as one that adapts to each students' needs. For example, I have always tried to frame questions in a different way so that the student can better understand the question. Some students need visual representations of numbers and systems to understand them, and others benefit more by understanding the concepts behind each formula. I prefer to tutor in math and physics, and especially with real world application problems. I hope to help students improve their standardized test scores and their understanding of the math and sciences so that they can achieve their academic goals! Hobbies: art, books, running, reading, music, writing

I am a published author who has enjoyed “coaching” our daughter, as she navigated through high school, college and graduate school. I mentor college juniors who are seeking careers in financial services, and I serve as a peer resource to professionals who are transitioning from private industry to the nonprofit sector. Hobbies: reading, cooking, writing, books, music, art, travel
Samuel
AP Calculus AB Tutor • +29 Subjects
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!
Quinn
Calculus Tutor • +17 Subjects
I am willing to address any issue with an open mind and I try to develop strategies that play to a student's strengths. I would like to think I am very approachable and personable, and I have had very positive experiences with many students in the past using this philosophy. Outside of academics, I love playing basketball and watching sports, as well as chilling with friends, listening to music, and keeping up with politics and current affairs.

Frequently Asked Questions
Students often find graph theory concepts—particularly proving properties of vertices, edges, and connectivity—challenging because they require both visual and abstract reasoning simultaneously. Combinatorics problems, especially counting techniques like permutations and combinations in complex scenarios, trip up many learners who haven't internalized when to apply which method. Proof writing in discrete contexts is another major pain point; students understand individual concepts but struggle to construct rigorous logical arguments that connect graph properties, set theory, or algorithmic reasoning into coherent proofs.
A tutor can break down proof construction by teaching you to identify the logical structure needed—whether you're proving by contradiction, induction, or direct argument—and then showing how to apply that structure to discrete objects like graphs or sets. They'll help you recognize common proof patterns in Discrete Geometry (like proving a graph is connected, or that a set satisfies a cardinality property) so you can apply similar reasoning to new problems. By working through proofs together and having you explain each step aloud, tutors help you see where your logic breaks down and build confidence in your reasoning process.
Many students struggle because algorithmic thinking requires you to think step-by-step about process and efficiency, not just whether an answer is correct—you need to understand *why* an algorithm works and when to use it. Problems involving shortest paths, sorting, or graph traversal demand this procedural-to-conceptual shift. A tutor can help by walking through algorithms visually (drawing out graph traversals, for example), having you trace through steps yourself, and then asking you to predict what happens if you change a condition—this builds the intuition that transforms algorithms from mysterious rules into logical tools you can reason about.
Visualization is critical in Discrete Geometry because graphs, trees, and networks are inherently visual objects—but being a strong visual learner isn't required. Many students who don't think of themselves as visual learners benefit from tutors who teach them to *create* their own diagrams systematically rather than relying on intuition. A tutor can show you how to translate abstract descriptions (like "a connected graph with 5 vertices and 7 edges") into drawings, and more importantly, how to use those drawings to verify your reasoning. This bridges the gap between abstract discrete concepts and concrete visual representation.
Gaps in set theory, basic logic (quantifiers, logical connectives), and modular arithmetic often undermine Discrete Geometry success because these concepts are used constantly without being explicitly reviewed. Students may also lack fluency with mathematical notation, which makes reading and writing discrete proofs feel overwhelming. A tutor can diagnose these gaps quickly and fill them in context—reviewing set operations or logical notation right when you encounter it in a graph theory problem, rather than as isolated review. This targeted approach helps you build confidence and see how foundational ideas connect to the discrete structures you're studying.
The challenge is recognizing whether a problem calls for permutations, combinations, the multiplication principle, or inclusion-exclusion—and students often memorize formulas without understanding when to apply them. A tutor helps by teaching you to ask diagnostic questions: Are we arranging or selecting? Does order matter? Are there restrictions or overlaps? By working through many problems and explicitly discussing *why* you chose a particular technique, you build pattern recognition that transfers to new scenarios. Tutors also help you organize your work systematically, showing all the reasoning behind your choice, which prevents careless errors and deepens your understanding.
Discrete Geometry can feel intimidating because it's often less familiar than calculus or algebra, and the jump from concrete procedures to abstract reasoning is steep. A tutor normalizes this struggle by showing you that confusion about graphs, proofs, and algorithms is universal—and that working through it carefully, with feedback, is how mastery develops. By celebrating small wins (understanding why a proof works, correctly identifying which counting method to use), tutors help you shift from "I don't get this" to "I didn't get it yet, but here's how I'll figure it out." This mindset change, combined with seeing concrete progress, builds genuine confidence.
Strong students develop habits like drawing or listing examples to understand a problem before attempting a proof, working backwards from what they want to prove, and testing their reasoning on small cases before generalizing. They also learn to break complex problems into subproblems—for instance, proving a graph property by first proving it holds for simple cases, then building up. A tutor teaches these strategies explicitly and helps you practice them until they become automatic. Rather than showing you the "right" answer, tutors guide you to discover these approaches yourself, which makes them stick and transfers to unfamiliar problems.
