Rhea
AP Statistics Tutor • +49 Subjects
I am a current student at the University of Chicago. I am working towards a Bachelor of Science in Biological Sciences, and I am on the pre-medical track. I am extremely passionate about tutoring, and I have several years of experience tutoring students in my high school's learning center in various subjects as well as tutoring private clients in Standardized Test preparation. Given that I graduated high school recently, I have taken several Standardized Tests and high school subjects myself, so I have a comprehensive understanding of not only how to tutor these subjects and exams, but also what it is like to take them. While I have a wide range of interests and am able to tutor various subjects, I am most passionate about tutoring in Standardized Test preparation (including ACT, SAT, SAT Subject Tests, and AP Exams), Biology, Chemistry, Math, and Spanish. I truly believe that students should have the opportunity to learn in the way that works best for them, and I love being able to help them succeed by creating a comfortable tutoring environment in which we can best assess their particular needs and use strategies specific to them. My passion for learning drives everything that I do, and tutoring is the platform that I use to try to spread that passion to others. In my free time, you can find me playing badminton, listening to music, or baking something (hopefully) delicious.
Matthew

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

Sharon
Pre-Algebra Tutor • +29 Subjects
I am a graduate of the University of Chicago, and I will be starting a graduate program at Columbia in August. I am about to complete a year of service with City Year, an education non-profit that places young adults into under-served schools. As a City Year member, I worked full-time in the classroom with middle-school students who were in approximately the 10th percentile for math (meaning they score lower than 90% of students). One-fourth of those students were able to grow around 15 percentile points by the end of the year! Hobbies: reading, cooking, gardening, music, art, nature, books, writing

Frequently Asked Questions
IB Computer Science SL students most commonly struggle with object-oriented programming (OOP) concepts like inheritance and polymorphism, understanding recursion and how to trace through recursive calls, and translating algorithmic thinking into actual code syntax. The transition from pseudocode to real programming languages trips up many students, as does grasping data structures like linked lists and trees—not just how they work theoretically, but how to implement and manipulate them. Additionally, students often find the computational thinking required for the exploration project challenging, since it demands both technical depth and the ability to document their design process clearly.
A tutor can teach you systematic debugging techniques like using print statements strategically, understanding error messages deeply (not just fixing the line that errored), and learning to isolate problems through test cases. Rather than jumping to solutions, expert tutors help you develop algorithmic thinking by walking through logic step-by-step, asking you to predict what code will do before running it, and building habits like writing pseudocode first. This approach transforms debugging from frustrating trial-and-error into a structured problem-solving skill that applies across all programming contexts.
The exploration project requires balancing technical implementation with clear documentation of your design process—something many students underestimate. A tutor can help you scope a project that's ambitious enough to demonstrate your skills but achievable within the timeline, guide you through iterative development with meaningful testing, and ensure your documentation (design specifications, code comments, and reflection) clearly shows your computational thinking. They can also review your code for efficiency and elegance, helping you move beyond "it works" to "it works well," which significantly impacts your final grade.
OOP mastery comes from building real projects where you design and implement your own classes, not just studying theory. A tutor can guide you through designing class hierarchies, understanding when to use inheritance versus composition, and implementing polymorphism in practical contexts. Working through code reviews where a tutor explains why certain OOP patterns are better than others—and having you refactor your own code to apply those patterns—builds deeper understanding than lectures alone. Starting with simple classes and gradually increasing complexity helps cement concepts like encapsulation and abstraction.
Recursion is hard because it requires thinking about a problem in a fundamentally different way than loops—you must trust that the recursive case works and focus on the base case and one level of recursion, not the entire chain. Tutors help by having you trace through recursive calls on paper with concrete examples (like calculating factorial or traversing a tree), visualizing the call stack, and then implementing recursion in small, manageable problems before tackling complex ones. The breakthrough usually comes when you stop trying to "see" the whole recursion and instead verify the logic at each level—a shift in thinking that a tutor can help you make.
Syntax errors are frustrating but ultimately less important than algorithmic thinking—the real skill IB Computer Science SL assesses. A tutor can help you move past syntax struggles by encouraging you to write pseudocode or flowcharts before coding, using IDE features like autocomplete and error highlighting effectively, and building familiarity with your chosen language through consistent practice. Once you've written pseudocode that clearly expresses your logic, syntax becomes a lookup task rather than a conceptual barrier. This separation of concerns helps you develop strong problem-solving skills even as your syntax fluency naturally improves.
Data structures make sense when you understand the problems they solve. A tutor can help you see why arrays are fast for access but slow for insertion, why linked lists excel at dynamic sizing, and why trees are perfect for hierarchical data—by having you implement these structures and use them in real projects. Rather than memorizing Big O notation, you'll experience performance differences firsthand by writing code that searches a sorted array versus a linked list, or by building a binary search tree for an actual application. This hands-on experience builds intuition that sticks far better than theory alone.
Beyond "does it work," good code review focuses on readability (clear variable names, logical structure), efficiency (avoiding unnecessary loops or redundant operations), and elegance (using language features appropriately). A tutor reviewing your code will highlight patterns you're missing, suggest refactoring opportunities, and explain trade-offs between different approaches. They'll also help you develop a critical eye for your own work by asking questions like "could this be clearer?" or "is there a more efficient way?" rather than just telling you the answer. This reflective practice is especially valuable for the exploration project, where demonstrating awareness of code quality directly impacts your grade.
