Pre-Algebra Tutor • +41 Subjects
I am a graduate of Washington University in St Louis, where I received my Bachelor of Arts in History with minors in Humanities and Anthropology. Since graduation, I have worked as a tutor, teacher, and director of tutors at a charter public middle school in Boston. During this time I also received my Masters in Mild to Moderate Disabilities from Simmons College. I have worked extensively with students with a range of abilities, including students with specific learning disabilities, emotional impairments, dyslexia, and ADHD. My teaching experience has given me a deep understanding of the knowledge and habits essential to academic success and has given me the opportunity to hone a variety of strategies that ensure students at each level can achieve their academic goals. While I tutor a broad range of subjects, my favorite ones are Reading, Elementary/Middle School Math, History, and Test Prep. In my experience, tutoring is the most rewarding when a student has that "aha!" moment and achieves a new level of understanding and confidence in his/her abilities. I am a firm believer in the transformative power of education, and I see my role to be that of a facilitator and coach who is there to help the student reach his/her goals through individualized support and rigorous practice. In my free time, I enjoy reading, running, practicing my Spanish, and discovering new music. I am also an avid traveler and just got back from a 3 month trip to South America. I look forward to the opportunity to work with you!

AP Calculus BC Tutor • +48 Subjects
I am an aspiring applied mathematician, with particular interest in image processing and climate science. I graduated in May 2017 from Washington University in St. Louis with a bachelor's in physics and mathematics, and am beginning a PhD program in September 2017 at the University of Chicago in Computational and Applied Mathematics. I've tutored introductory physics students for three years and enjoyed it thoroughly, as a chance to help other students while revisiting fundamental concepts to enhance my own knowledge. I'm eager to continue reaching out and helping students of math and physics to succeed and, furthermore, to appreciate the beauty and power of these subjects.
Ingrid
Pre-Algebra Tutor • +51 Subjects
I am exploring my creativity by pursuing a double major in Asian Languages and Cultures with a focus in Korean, studying abroad in South Korea as a Benjamin A. Gilman Scholar, leading workshops that teach 3D printing and CAD for undergraduate students as the president of 3D4E, advocating for the first-generation and low-income student community as the Outreach Chair of the Quest+ Scholars Network, and getting involved with the Society of Women Engineers' outreach committee. I currently hold a work-study position as an administrative clerical aide in the Institute of Sustainability and Energy at Northwestern and was an undergraduate researcher in the John Rogers Lab. As I look forward with aspirations of applying to graduate school, areas of research in biomedical engineering and biotechnology that I am particularly interested in include biomaterials, pharmaceuticals, and drug delivery systems. Outside of the classroom, I enjoy learning on my own and sharing my experience and knowledge with my peers and other students. I hope to make use of my experiences with academics and learning in high school and so far in my undergraduate career in order to effectively tutor students who may be experiencing the same struggles in learning that I also experienced.

I am currently attending Johns Hopkins University, pursuing a dual degree in Computer Science and Applied Math and Statistics. I love helping students and I love the feeling I get knowing that I was able to use my knowledge to make someone else happier. My favorite subject to teach is math because there are so many ways to learn it and if one way does not help I can use another. I used to teach taekwondo and interacted with all kinds of students, and I'm excited to help out more! Hobbies: books, reading, music, writing, art

Elena
Calculus Tutor • +32 Subjects
I am a graduate of McGill University (BA First Class Honors) and the University of Edinburgh (MSc First Class Honors with Distinction) with over eight years of tutoring experience. I am currently a curriculum developer for a company which creates relatable and culturally-literate courses for middle and high-schools, and am particularly adept at communicating and explaining concepts in a quirky, engaging, and intelligent manner. I was named Scotland International Young Thinker of the Year 2014 for exactly that sort of work. Much of my tutoring background is in test-prep and essay coaching, which I enjoy because it allows the tutor and student to think strategically together, and work as a team to achieve concrete results. I have worked with students ranging in age from 6-32, and believe that, in an educational context, a few jokes never hurt anybody. I love reading and learning, and my educational approach is centered around making the material just as engaging to students as it is to me. I think J.K. Rowlings, the writer of Harry Potter, is just as brilliant as Stephen Hawking, and in my free time, I manage my (terrible) fantasy baseball team, write songs for my comedy band, and crack jokes about terrible science-fiction movies with my friends.

Calculus Tutor • +38 Subjects
I am a graduate of the University of Chicago where I received my Bachelor of Arts in Philosophy. Currently, I am in the master's program at the University of New Mexico where I am continuing my education in philosophy. Ultimately, I hope to go on to earn a PhD in Philosophy so that I can continue engaging in my passions for learning and teaching. While in school, I have spent countless hours coaching high school speech and debate both in person and working online with students across the country. My focus in coaching has been to emphasize philosophy and critical thought to prepare students to think through novel arguments on their own. I am passionate about teaching and tutoring because I love seeing students learn to be intellectually independent and think through problems on their own terms by developing their critical thinking skills. I have devoted my life to education because I am passionate about it, and I try to share some of my passion for learning with the students I work with. I tutor all sorts of Standardized Tests, and I particularly enjoy working on logic-based problems like analogies and math sections. When I am not tutoring or reading for school, I enjoy strategy games (both board games and video games), listening to music, hiking, playing basketball, and just relaxing with friends.
Isabella

I am a graduate of MIT. I received my Bachelor of Science in Mathematics with minors in Management Science and Ancient and Medieval Studies. Since graduation, I have started my PhD at Georgia Tech in Operations Research. Throughout my career I have TA'd several math and computer science courses at the college level. I have also taught at summer programs for gifted middle school and high school students. I am passionate about tutoring kids in math and science because I think that a strong foundation in STEM at an early age can set the tone for their future. In my spare time I like to engage in athletics, and was a Division 1 rower in college. Hobbies: reading, swimming, writing, books, music, running, art
James
AP Calculus AB Tutor • +41 Subjects
I am currently a senior at Harvard College where I study chemistry, and I'll be attending Columbia Medical School next year. I have years of experience tutoring college students in math (mostly calculus) and chemistry including both general and organic chemistry. In addition, I am very familiar with all sections of the SAT and ACT having prepared several high school students for these tests. I believe that every student is capable of boosting his or her baseline score on these tests, so long as he or she works hard to get to know the format of the tests and the most popular types of questions. I tutor because I love seeing students develop a genuine passion for the subjects they once disliked (such as math and science), once they understand the power of these subjects and their applications to the real world.

Frequently Asked Questions
Students often find object-oriented programming (OOP) principles—particularly inheritance, polymorphism, and encapsulation—challenging to apply in practice. The transition from understanding syntax to designing robust algorithms and data structures (trees, graphs, sorting/searching) trips up many learners. Additionally, the Internal Assessment (IA) project requires students to independently plan, develop, and evaluate a solution, which demands both technical depth and clear documentation—skills that don't always develop naturally from exam prep alone. Tutors can break down these abstract concepts with concrete examples and guide students through the IA process step-by-step.
Effective debugging starts with understanding what your code is *supposed* to do, then systematically isolating where it diverges. Use print statements or a debugger to trace variable values at key points, test edge cases (empty inputs, boundary values), and read error messages carefully—they often pinpoint the exact line causing problems. Many IB students jump straight to rewriting code when a methodical approach would save time. A tutor can model this debugging mindset, teach you to read stack traces, and help you develop the habit of testing incrementally rather than writing large blocks before checking if they work.
Syntax is the grammar of a language (how to write a for loop or declare a variable), while algorithmic thinking is the logic of *solving* a problem (breaking it into steps, choosing the right data structure, analyzing efficiency). You can memorize syntax quickly, but algorithmic thinking requires practice designing solutions, understanding trade-offs (time vs. space complexity), and recognizing patterns across different problems. IB Computer Science HL exams test both, but the harder questions reward algorithmic insight. Tutors help you move beyond "how do I write this?" to "what's the best way to solve this problem?" by working through problems together and asking you to explain your reasoning.
The IA requires you to identify a problem, design a solution, code it, and write a detailed report—all independently. A tutor can help you scope a project that's ambitious enough but achievable, guide you through planning (pseudocode, data structures, user interface mockups) before you code, review your implementation for code quality and efficiency, and help you articulate your design decisions and testing approach in your written documentation. They won't write the code for you, but they'll ask clarifying questions that push you to think deeper about your choices and catch common pitfalls like poor variable naming or missing edge case handling.
Code review forces you to read and understand someone else's logic (or your own code from weeks ago), which builds the critical thinking skills IB exams test. It exposes you to different approaches and helps you recognize when code is inefficient, hard to follow, or missing error handling. During tutoring sessions, a tutor can review your code, ask why you made certain choices, suggest refactoring opportunities, and model how professional programmers think about readability and maintainability. This practice also directly prepares you for the IA, where examiners evaluate not just whether your code works, but how well it's designed and documented.
Choosing the right data structure depends on what operations you need to perform frequently. If you need fast lookups by key, use a dictionary or hash table; if you need ordered access or frequent insertions/deletions at the middle, consider a linked list; if you need a hierarchy, use a tree; if you need to explore connections, use a graph. IB Computer Science HL emphasizes understanding *why* a choice matters—arrays are fast to access but fixed-size, while linked lists are flexible but slower to search. Tutors help you practice this decision-making by presenting problems and asking you to justify your structure choice, then analyzing the trade-offs in time and space complexity together.
Exam questions test your ability to write correct code quickly under time pressure, often with limited context and no ability to test incrementally. Real projects let you plan, iterate, debug, and refactor over time. IB Computer Science HL students need both skills: the precision and speed for Papers 1 and 2, and the planning and independence for the IA. A tutor can help you practice timed coding problems to build fluency, then shift gears to guide you through the messier, more realistic process of designing and building the IA project. This dual focus ensures you're prepared for both the exam and the practical programming skills the course is designed to teach.
Beyond knowing the language and curriculum, a strong tutor understands the IB assessment criteria (especially for the IA) and can explain not just *how* to code, but *why* certain approaches are better. They should be comfortable debugging with you, asking questions that help you think through problems rather than giving answers, and recognizing when a student is stuck on syntax versus stuck on logic. They should also have experience with the programming language(s) used in your course (Python, Java, or C++) and be able to relate coding concepts to real-world examples. Look for tutors who ask about your goals—whether you're aiming for exam mastery, IA success, or both—and tailor their approach accordingly.
