Ankit
AP Statistics Tutor • +48 Subjects
I am Ankit Jajoo. I am enrolled in Duke University Class of 2022 studying neuroscience and computer science. STEM is my number one passion, while history is my number one interest. Humanities and STEM not only coexist, but work together often in life. While STEM provides the foundation for the future, humanities contributes to how it is used to advance humanity as a whole. I love biology, chemistry, and computers. It is so cool to see how all these tiny minute parts of the world interact to create you, me, and everything we touch. On the other hand, history is cool to see how societies interacted to create the present world. The past is never separate from us, but always influencing everything from the various countries to cities to the tiny villages all over the world. The world is a combination of all of this and it is my passion to understand the world. Other than just about education and information, I love teaching other people about stuff. I enjoy teaching all my friends some stuff, in return they teach me other stuff. Contrary to popular opinion, teaching is a two way street. I've learned a tremendous amount from students and I hope they learned a similar amount from me. Tutoring students in a field I enjoy such as STEM or history is a dream come true.
Dylan
AP Calculus BC Tutor • +44 Subjects
I'm a sophomore at Vanderbilt University, majoring in Physics and Classics and minoring in Mathematics and Computer Science. I'm qualified to teach a wide variety of subjects, but prefer to focus on the fields I'm studying in school listed above; I have a passion for those areas that I want to share with everyone, no matter the education level or confidence. I believe that no one is "bad at math," but many people haven't been taught math and science concepts in a way that matches how they best learn. As a result, I try to tailor my teaching style to be the best it can be for each individual student. With regard to math and physics, I myself prefer a physical, graphical understanding of different concepts, so I do best at explaining what seemingly abstract concepts actually mean in the real world and how they act on a graph.
Anna
Middle School Math Tutor • +49 Subjects
I am very passionate about teaching material in a way that works with each student's personal learning needs and making sure that they understand the material at its core, not just how to answer a test question. Because I majored in Neuroscience, I have expertise in a wide range of sciences, as Neuroscience is a very interdisciplinary subject. I have also had extensive experience in Computer Science. Outside of Neuroscience, I devoted a lot of time to studying the humanities. I even started a blog my junior year as an outlet to further pursue these academic interests! As a result, I also enjoy tutoring in Literature, English, and Writing. Hobbies: art, books, reading, music, writing
Rhamy
AP Calculus BC Tutor • +54 Subjects
I am a Thomas Jefferson High School for Science and Technology graduate and currently attend Vanderbilt University majoring in Computer Engineering with a minor in Business. I've tutored in various subjects for about 6 years now. I've done it so much, one of the companies I started was tutoring-based. In all, I am a technology-oriented entrepreneur, an impact-driven member of the community, and a striving academic. My passion for computer engineering and dedication to solving the world's problems push me to continue to be better tomorrow than I am today. I am currently pursuing a career in engineering and business where I hope to improve the lives of those around me every step of the way.
Brice
AP Calculus BC Tutor • +47 Subjects
I am an undergraduate student at the Massachusetts Institute of Technology, and I have tutored students since my early high school years. I've had experience instructing and guiding a variety of students, from young middle schoolers taking their first steps into the world of computer programming to my own peers struggling with their calculus exams. Over the past year alone, I've worked with over 30 students, spending several hours each day to help them stay up to speed on their schoolwork. I specialize in many areas of math as well as computer science, biology and physics. When tutoring students, I draw on my own experience with learning the material to identify and address the obstacles they face. I believe that promoting a deeper level of understanding of the subject, as opposed to merely teaching to the test or problem set, will enable students to excel in the long-term. Hobbies: reading, music, writing, art, books

Frequently Asked Questions
Score improvement depends on your starting point and how consistently you engage with tutoring. Students who work with tutors typically see meaningful gains—often 1-2 score points—when they focus on weak areas like object-oriented programming concepts, array manipulation, or the free-response section. The key is identifying exactly where you're losing points (conceptual gaps vs. timing issues vs. debugging skills) and targeting those specific challenges.
Most students benefit from starting tutoring 2-3 months before the exam, though earlier prep gives you more time to build a strong foundation in Java fundamentals and problem-solving patterns.
The free-response section requires you to write code from scratch, which is fundamentally different from the multiple-choice section. Success comes down to three things: understanding the problem completely before coding, writing clean code with proper structure, and testing your logic mentally as you go.
Many students rush into coding without planning, which leads to syntax errors and incomplete solutions. Experienced tutors help you develop a consistent approach: read carefully, outline your solution, write modular code, and leave time to review. Practice with actual AP free-response questions under timed conditions is essential—this builds both accuracy and confidence in your problem-solving approach.
Most students struggle with a few core areas: 2D arrays and nested loops, inheritance and polymorphism, and ArrayList operations. These topics require understanding abstract concepts and applying them to solve problems—not just memorizing syntax.
Additionally, many students underestimate the reading comprehension required on the exam. Questions often describe complex scenarios or code segments, and you need to trace through logic carefully. Tutoring helps break down these challenging topics into digestible pieces and gives you practice explaining what code does, which deepens your understanding far beyond just writing code yourself.
The exam has two sections with tight timing: 90 minutes for 40 multiple-choice questions (roughly 2 minutes per question) and 90 minutes for 4 free-response problems (roughly 22-23 minutes each). Many students get caught up in difficult multiple-choice questions and run out of time, or they start coding free-response problems without thinking them through first.
A smart strategy is to move quickly through multiple-choice questions you know well, flag challenging ones to return to later, and allocate your free-response time wisely: spend 3-4 minutes reading and planning, 15-18 minutes coding, and a few minutes reviewing. Practicing with full-length practice exams under timed conditions is the best way to develop your personal timing rhythm and identify where you tend to lose time.
The best tutors for AP Computer Science A have strong Java expertise and understand the exam's specific expectations—they know which topics are heavily tested, what the free-response rubric values, and how to help you move beyond just 'getting code to work' to writing clean, efficient solutions.
Look for someone who can explain concepts in multiple ways (not just show you code), who asks you questions to deepen your thinking, and who gives you realistic feedback on your progress. They should also be comfortable diving into test-taking strategy, not just subject content—helping you manage timing, debug under pressure, and approach unfamiliar problem types with confidence.
Ideally, you should be working through the AP Computer Science A curriculum during the school year, so by January or February, you can shift into targeted test prep mode. This gives you 3-4 months to review weak areas, practice problem types, and take full-length practice exams.
If you're starting closer to the exam date, focus on diagnosing your weakest topics immediately and prioritizing high-impact areas like arrays, inheritance, and free-response strategies. Even 4-6 weeks of focused tutoring can help you solidify shaky concepts and improve your approach to the exam, though earlier prep is always better for building deep mastery.
Test anxiety in computer science often stems from fear of the blank screen—facing a free-response problem with no code starter can feel overwhelming. The best antidote is practice and familiarity. When you've solved dozens of similar problems and have a consistent approach, you build confidence that you can handle whatever appears on exam day.
Working with a tutor also helps because you get low-stakes practice and feedback in a supportive setting. You learn that mistakes are learning opportunities, not disasters. Additionally, reviewing your thought process—how you approach problems, how you debug errors, how you manage your time—removes some of the mystery and control from your hands, which itself reduces anxiety.
