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.

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!

Knowledgeable MCAT tutor

The first lesson with Dr Lester was a great experience. In just one session, he had explained the various strategies that can be applied to the CARS section and he uses relatable examples to aid the understanding of how they can be applied. In addition, he is also very knowledgeable in other sections as he teaches the type of information worth spending time on. A friendly and patient tutor that you can approach if you have any questions.

MCAT Tutoring Session

I had my first MCAT tutoring session with Lester G., and it was a great experience. He was patient, knowledgeable, and did an excellent job explaining concepts in a way that made them much easier to understand. He also shared helpful strategies for approaching MCAT passages and questions, which gave me a new perspective on how to tackle the exam.

I highly recommend him to anyone looking for a supportive and knowledgeable MCAT tutor.
