Amy
College English Tutor • +13 Subjects
I have a B.A. in French and a diploma in Business French from the Chamber of Commerce and Industry in Paris. I also speak Greek, Italian, and Spanish.I have worked as a private tutor in the area of foreign languages, essay writing, and a variety of other subjects for more than a decade. In that time, I have witnessed the difficulties many students have when learning something that seems unfamiliar, uninteresting, or just makes no sense. Seeing this, I believe it is my responsibility to be a positive influence by ensuring that all my students do well and understand the material. For example, with French, I always give them a brief English grammar lesson beforehand which helps tremendously boost their confidence level as the foreign gradually becomes familiar.I am truly excited about working with students and encouraging them to excel. There is nothing more gratifying than seeing a student conquer his/her fears and expressing him/herself in a way he/she never thought possible. I work with each student’s specific needs in a patient yet firm manner. I also exhibit determination, empathy, and humor to make learning an enjoyable and rewarding experience. Most importantly, I am personable and understanding and believe that brings me closer to helping my students.In my free time, I love cooking Mediterranean/Greek cuisine and would love to open a restaurant one day. I also write poetry, short stories, etc. and am currently working on my first novel. Lastly, I adore knitting and crocheting cute, fashionable clothes and accessories for girls.
Gabrielle
AP Biology Tutor • +25 Subjects
I am recent graduate of Binghamton University, with a Bachelor of Sciences in Biology. I am deeply committed to the value of education, and believe that learning is a gift and an opportunity for growth that should be available to everyone. For this reason, I am passionate about tutoring and helping students, so that everyone is able to not only do well in school, but to fall in love with learning in the process. Anyone can enrich themselves through learning. This is the foundation of my teaching philosophy: in addition to emphasizing results and academic achievement, I believe it is integral to find an individual approach to each student and to focus first and foremost on teaching students to study in a way that is effective and engaging. I tutor elementary, middle, and high school students in all subjects. In my free time, I like to go running, practice dance, learn new languages, and play ping-pong.

One area where we seem to have the mostfun is prepping for exams and writing assignments. I am a firm proponent ofeducation, and as a tutor, my approach is based on each of my students'level of proficiency, their goals, and their learning pace. I focus on providinga pleasant and safe experience for my students. I prepare lesson plans that arecreative and introduce new topics in a fun way, spending enough time reviewingthe material. Afterwards, I allow students time to practice on their own. I encourage you to contact me to schedule so togetherwe can start achieving your goals
Anna
ACT Writing Tutor • +27 Subjects
I honestly love tutoring. While working in finance and publishing over the past decade, I have independently tutored students from many premiere NY and NJ high schools and universities. I continued tutoring even after joining a major private equity firm because of how much I enjoy working one-on-one with students. Breaking down seemingly complex subjects is one of my favorite pastimes--it's part of the reason I also enjoy writing about arcane financial topics like quanto spreads on sovereign CDS. I've also developed a newfound respect for the challenges students face when undergoing years of testing after developing my own study plan to pass the first two CFA exams (I'm taking the third exam in June). This experience has shaped how I work with students to tackle test-taking anxiety and master difficult material quickly.I have both a BA and MA in English from New York University.
Catherine
Algebra Tutor • +15 Subjects
Hello! My name is Catherine Raj and I am a second-year medical student at Ohio University Heritage College of Osteopathic Medicine. I graduated from The Ohio State University with a Bachelor's of Science in Neuroscience in 2022. Since 2015, I have tutored children from ages 3-16 in areas of math and reading, as well as their school curriculum. Apart from tutoring here, I have worked for the Kumon Learning Center as a teaching instructor for 5 years. While I am certified to tutor a broad range of subjects, I have years of experience with tutoring young children in math and reading, such as addition, subtraction, multiplication, division, phonics, reading comprehension, and much more. I connect with elementary and middle school students very well, as I believe in understanding children in order to give them a fulfilling tutoring experience. I also very much enjoy tutoring pre-algebra and algebra as those are my favorite math subjects, as well as my best! My students and I have always had a deeper level of understanding beyond the books and I pride my style of teaching on that aspect.

Chester
Creative Writing Tutor • +18 Subjects
I love English, and good writing. Since I like working one-or-one or with a small group, tutoring is a great way for me to help young people communicate more effectively in writing. As a social scientist, I also like to talking about statistics and social science. I like to teach by example and ask lots of questions so students can discover answers themselves. When not working, I like to watch movies, exercise, and write science fiction.
Maria
ACT Prep Tutor • +15 Subjects
I received my Bachelor of Science degree in Biochemistry from Denison University. I am currently pursuing an M.D. at Case Western Reserve University. I've been a college-level teaching assistant for both introductory biology and general chemistry. Besides chemistry, I really enjoy tutoring for test prep (ACT and MCAT) because I view these types of tests to be a collection of puzzles to solve. It's a lot of fun helping students to figure out the logic behind these puzzles and apply it broadly, and it's incredibly rewarding to see this integration of knowledge translate to a high score. When working with students, I like to challenge them to identify the purpose of the problem or question and what underlying reasoning can be applied broadly in future questions. In doing so, students gain more long-term usable skills and the ability to think independently.

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.
