About Lester

Bio

I am a current medical student and a graduate of Johns Hopkins University, where I completed my studies in Biomedical Sciences. My academic background has given me a strong command of the material tested on the MCAT, as well as an understanding of how to apply that knowledge in a clinical context. In addition to my education, I bring over 10 years of experience as a standardized test-taking specialist, during which I have worked with hundreds of students ranging from high school to college...

I am a current medical student and a graduate of Johns Hopkins University, where I completed my studies in Biomedical Sciences. My academic background has given me a strong command of the material tested on the MCAT, as well as an understanding of how to apply that knowledge in a clinical context. In addition to my education, I bring over 10 years of experience as a standardized test-taking specialist, during which I have worked with hundreds of students ranging from high school to college and non-traditional applicants. I have supported students in both one-on-one and small group settings, helping them strengthen their foundations and improve performance on high-stakes exams like the MCAT.

My tutoring approach is centered on a Socratic method, where I guide students through questions and reasoning rather than simply providing answers. While I do reinforce key content, my primary focus is on teaching students how to take the test. I help students develop a structured approach to breaking down passages, identifying what questions are truly asking, eliminating incorrect answer choices, and managing time effectively. This approach builds critical thinking and confidence, allowing students to move beyond memorization and perform consistently under pressure. My goal is to equip each student with a repeatable strategy so they can approach the MCAT with clarity, control, and the skills needed to achieve their target score.

I come prepared with the resources, strategies, and personalized support needed to make each session productive and goal-focused.
Anatomy

Anatomy

I have extensive experience tutoring Anatomy and Physiology, with a strong background in medical-science level content and exam-focused instruction. I help students build a clear understanding of anatomical structures, physiological processes, and the relationships between systems, while also strengthening the reasoning skills needed to succeed on quizzes, exams, and cumulative assessments. My approach is structured, clear, and adaptable to each student’s needs. I am especially skilled at breaking down complex material into manageable steps, using clinically relevant explanations, active recall, and guided practice to improve retention and confidence. I also emphasize practical study strategies that help students master both memorization-heavy material and application-based questions.

HIghly experienced & knowledgeable tutor!

In just one session, Lester helped me so much with understanding the structure of AAMC passages, especially in the CARS section. He is extremely knowledgeable and takes his time in his teaching to explain why each strategy works. I have already seen how I can utilize the skills I've learned from him!

Super Attentive and Direct

Great first session with Lester. He checked in constantly to make sure I was following, so questions never piled up until the end. He gave me practical strategies for attacking passages and timing, plus specific tips for CARS and set me homework to keep the momentum going (morning/evening rituals). My past scores have intimidated other tutors but he was genuinely excited to work with me, and that energy made me want to study more. Looking forward to the next sessions!

Really Helpful MCAT Tutor!

I've really enjoyed my sessions with Lester! He's patient, knowledgeable, and does a great job explaining things in a way that's easy to understand. What I appreciate most is that he doesn't just tell me the correct answer, but actually helps me understand my thought process and where I might be going wrong. He's taught me different strategies for approaching CARS questions, which has made reviewing passages a lot more manageable. I've really appreciated his help so far and would definitely recommend him.

Efficient and Prepared

Lester is very focused with the time he spends teaching me - it is easy to tell how prepared he is. He has helped me to understand how to make the most of my time by trying to master the test rather than getting lost in the details. His help and been very valuable in my experiences with him so far.

Best tutor ever

This guy is the goat😭 he knows what he’s talking about, clearly has a ton of experience, and gets straight to the point while also listening to your perspective. I tried multiple other tutors but genuinely none come close. I was sold on the very first session in which my mind was blown on all the strategies he went over in the span of an hour. I genuinely want to continue working with him. Keep it up!

Great MCAT CARS Tutor — Knowledgeable and Helpful

Lester has been helping my daughter with the CARS section of the MCAT, and so far we have been very pleased with him. He seems very knowledgeable, patient, and familiar with the strategies needed for this challenging section of the exam. We would like to continue working with Lester for several more sessions so we can see how his tutoring translates into improvement in her MCAT CARS score. Based on our experience so far, I believe he can be a great resource for students preparing for the MCAT, and I would recommend him to others looking for help with CARS.

best MCAT tutor ever

Lester is genuinely one of a kind, he was so patient with my session and is clearly very knowledgeable. He broke down my fl score and was able to identify my weak points to tailor the lesson to help me close any gaps I have. I’m so happy I found him and I’d recommend him to anyone needing some extra guidance during their MCAT prep!

Knowledgeable, Patient, and Encouraging

I had my first session today with Lester, and I couldn’t be more grateful that I chose him to help me with my MCAT studying. Right from the start, he was able to identify my weak points, especially when it comes to test taking, and he has a great ability to distinguish what’s truly high-yield from what isn’t worth spending too much time on. I was also able to ask him about specific content questions I had been struggling with, and he explained everything in a way that finally made sense to me. He was extremely patient and made me feel completely comfortable asking questions, even ones I worried might be “dumb.” After just one session, I already feel like I learned so much and have a better understanding of how I should approach my studying and MCAT questions. I’m really looking forward to continuing to work with Lester and becoming more confident in my test-taking abilities. I genuinely feel like he’s the right person to help me get there!

Very knowledgeable and insightful tips for the MCAT

Lester is very knowledgeable about the ins and outs of the MCAT. His advice on the CARS specifically is very methodical and provides a framework to understand how to succeed on the section. Moreover, he’s always sure to stop and ask for questions and provide clarification. Highly recommend!
