I'm am a Princeton Review-certified MCAT instructor and medical doctor with an M.D. from Johns Hopkins Medical School, scoring in the 99th percentile on the MCAT. My passion for teaching began in college, where I served as the Head Biochemistry Teaching Assistant, providing a weekly review lecture that ended up having better attendance than the normal lectures. Since then, I have worked with hundreds of students, both first-time test takers and retakers, guiding them to significant score improvements—including increases of 10+ points and multiple 515+ scores.

With years of experience tutoring the MCAT in both one-on-one and group settings, I understand that success on this exam requires more than just content knowledge—it’s about efficient study strategies, test-taking skills, and mindset. Many students feel overwhelmed by the sheer volume of MCAT resources, but I cut through the noise, providing structured study schedules, resource guidance, and accountability coaching tailored to each student’s needs.

Whether you’re struggling with biochemistry, physics, or strategy refinement, I tailor my approach to your specific weaknesses, ensuring understanding over memorization. My students describe my teaching style as clear, engaging, and highly effective, and I take pride in making difficult concepts accessible.

If you're serious about improving your MCAT score and want a dedicated tutor with a proven track record of success, I’d love to help you reach your goal. Let’s get started!

MCAT

I am a medical doctor (M.D.) from Johns Hopkins and am a former Princeton Review MCAT instructor with 5+ years of experience tutoring both one-on-one and in class settings. I scored in the 99th percentile on the MCAT and have helped students improve their scores by 10+ points. My teaching experience began as the Head Biochemistry Teaching Assistant in college, where I gave a weekly review lecture that was more well attended than the actual lectures. While most MCAT teachers specialize in certain subjects, I'm adept at all of them and focus on teaching at the intersections of the subjects, which is what the MCAT tests for. My approach focuses on efficient study techniques, deep understanding of the concepts, and critical thinking skills to help students maximize their MCAT performance.

Great MCAT Tutor

I’ve been working with Joohun for a couple of months now to prep for the MCAT, and it’s honestly made such a big difference. What makes him stand out from other MCAT programs is how personal and supportive he is. He doesn’t just go through the motions or use a one-size-fits-all approach—he takes the time to figure out exactly where I’m struggling and adjusts each session to focus on what I need most. He has a way of explaining things that makes sense, even with the most complicated topics, and he’s incredibly patient when I need a little extra time. Thanks to him, I don’t just feel more prepared—I believe I can do this. What I appreciate is that he doesn’t just teach the content. He helps you think like a test-taker. He’s shown me how to approach tough passages, manage my time better, and stop second-guessing myself. Because of that, I feel way more in control when I’m doing practice exams. His encouragement and consistency have made the whole studying process feel a lot less overwhelming, even on the hardest days.

AMAZING Tutor!

From the very first session, it was clear that Joohun not only knew the material inside and out, but also understood how to teach it in a way that made everything finally click. What sets him apart is his ability to break down complex passages and walk me through the strategy step by step, making sure that I understood the “why” behind each answer. If I hit a wall or felt stuck, he never hesitated to shift gears—finding new ways to explain the material or simply giving me space to process. His patience and willingness to meet me where I was made all the difference. As someone who graduated from medical school, Joohun also gave me insightful advice about the application process and what to expect beyond the MCAT. His support went beyond content review…he truly cared about my success and well-being. He helped me push through rough days and reminded me why I started this journey in the first place. If you’re feeling discouraged, overwhelmed, or just need someone to guide you through this grueling process, Joohun is your guy. He is not just an exceptional tutor…he’s a dedicated mentor and a genuinely kind person who is invested in your success. I honestly wish I had found him from the start. You will not regret booking Joohun, I can’t recommend him enough!!!

Best MCAT Tutor!

I honestly can’t recommend Joohun enough. He is hands down the best MCAT tutor I could have asked for! From day one, he really helped me stay on track by providing a structured and tailored study plan that kept me organized and focused. But what really sets Joohun apart is his ability to pinpoint exactly where I was struggling and offer effective strategies to overcome those challenges. One of the biggest hurdles I had was tackling certain subjects that I had been avoiding. Joohun was super supportive throughout this process, helping me build confidence and slowly ease into these tricky areas. His guidance made all the difference in turning those weak spots into strengths. Every session with Joohun was not only productive but also enjoyable. He has an amazing way of breaking down even the most complex concepts into easily digestible pieces, making studying feel less overwhelming. No matter how difficult the material was, Joohun’s explanations were always clear and concise. I also truly appreciated how patient and kind he was when I got frustrated or discouraged. Joohun doesn’t just teach the material. He teaches you how to approach learning with confidence and compassion for yourself. Even when I doubted my progress, he helped me stay grounded, reminding me that improvement takes time and encouraging me to be kinder to myself. His support went far beyond academics, and that made a huge difference. What really blows me away is how much progress I made in just a few sessions with him. I wish I had found him sooner because I honestly feel like I covered more ground in those few weeks than I did in months of studying on my own. Joohun is simply phenomenal, and if you’re serious about acing the MCAT, he is the tutor you need. I wholeheartedly recommend him!

Very Qualified and Organized Tutor

As someone who had not met with an MCAT tutor before working with Joohun, I was presently surprised. I truly believe that Joohun is a quality tutor worth the time and the money. I appreciate that he gives me studying structure and specific things to work on throughout the week in between sessions. He is also big on accountability which was something that was very important to me when looking for a tutor. Each tutoring session we have a mini lesson that is very interactive. He provides me with questions to answer and makes sure I am understanding the content as we go. It is apparent to me that he knows what strategies and habits are important to succeed on the MCAT. I would definitely recommend Joohun to anyone looking for MCAT studying help.

The Best MCAT Tutor: Knowledgeable, Engaging, and Truly Invested in Your Success

To put it simply, I would recommend Joohun above anyone for the MCAT if he is available. He is incredibly patient and knowledgeable and can break down any complex concept in a simple manner. But he is also engaging. He turns learning into an active process, making lessons feel like a dialogue and making sure students understand the material well enough where they could teach the concepts themselves if need be. I worked with several other tutors before for the MCAT. And those experiences helped me realize how much more effective and skilled he was. His explanations, personable nature, and dedication to his students' success set him apart. His experience in working with neurodivergent students and guiding them through the accommodation process were also invaluable to me. Beyond just MCAT prep, he has gone above and beyond to support me in every aspect of my medical school journey, from refining my personal statement to strengthening my application essays. His guidance and life experience have profoundly shaped the way I learn and approach materials. Beyond academics, he shared invaluable lessons about perseverance through hardships and learning from failure—insights that will stay with me not only through medical school but throughout my future career.
