I am a MD resident physician in Radiology and 2020 graduate of Rice University. Throughout my academic and professional journey, I've found that one of the most rewarding parts of education is helping others reach their potential. I've worked with students across many stages, from high schoolers preparing for the SAT/ACT, to applicants refining personal statements for college and medical school, to medical students tackling board exams. In each of these settings, my goal remains the same: to help students not just learn material but learn how to learn. My teaching philosophy is built on the belief that success doesn't depend on being naturally gifted, it comes from consistency, structure, and a willingness to improve. I work with students to develop individualized study plans, set achievable milestones, and build momentum. I focus on helping students become confident learners who can approach problems with clarity and strategy.

I've spent 6 years tutoring K-College-level students in a variety of subjects, from ACT and MCAT to neuroscience and basic reading. My job is to find where the confusion actually started and make a plan. We work through it out loud until you can explain it back to me. Students leave my sessions not just with the homework done, but knowing how to attack the next problem on their own. I graduated from Ohio State with a 3.96 GPA, 34 ACT and a 517 MCAT score.
I am currently a medical student at the University of Texas Southwestern. I completed a major in Biology with a triple minor focus in Chemistry, Sociology, and Medicine and Society. During my undergraduate career, I tutored hundreds of students through my work with the American Chemical Society, LAUNCH, and Scholars Enrichment Program. While I tutor a broad range of subjects, I am most passionate about Chemistry and Organic Chemistry. I have recently taken my MCAT and I would love to help you prepare for that especially if you need help with Chemistry based questions. In my experience helping struggling students prepare for Standardized Tests such as the ACT and the MCAT, I always find new ways to engage my students and make testing strategies more accessible to them. I believe the best way to learn is to teach. Therefore, my main teaching strategy will be filling any knowledge gaps and allowing you the opportunity to re-explain material in order to ensure you will remember it.
I am a graduate of Emory University, where I received my Bachelor of Science in Neuroscience and Behavioral Biology with a minor in Dance and Movement Studies. Throughout college, I have trained extensively tutoring students of various ages across many subjects. As an "Emory Reads" tutor for four years, I helped alleviate education inequality by providing weekly tutoring to students in Atlanta's lowest performing elementary schools to enhance reading comprehension and mathematics skills. I worked with the schools to transition engaged learning to an online format. I am a firm proponent of education, and am committed to providing my students with the best learning experience achievable. I am passionate about helping struggling students face the challenges of early education, and help them build a solid foundation for the future. I also served several semesters working with high school and college-age students. As a Teaching Assistant for college-level physics, I developed a sincere bond with my students as I strived to help them achieve there academic goals. I also worked as a peer-editor for papers and personal statements, as appointed by my professors who recognized my strong writing skills. For three years, I tutored and mentored high school students who were passionate about pursuing the sciences in college. I helped them through their AP coursework, preparing for standardized tests, and the college application process. I have worked with students to get into Ivy League universities, Berkeley, UCLA, NYU, and more. I am looking forward to being able to helping every student reach their personal potential, and sharing the joy of eventual success!
Howdy! My name is Karthik, and I look forward to meeting you. I've been tutoring for over 10 years, and am excited to give you the tools to achieve success! I've seen it all, from frustrated parents who need their 8 year old to learn how to read, to high school/college students just needing a grade boost to pass a class, to retirees who finally have enough time to pick up that language they never got around to. I've personally taken courses on, passed tests for, and used the knowledge in real life for all the subjects I tutor, so I know not just how to learn, but also how to apply. If you'd like to get your personlized gameplan to never need tutoring again, help me help you and book a session today!
I am a current osteopathic medical student with a strong passion for teaching science in a way that feels approachable and understandable. Throughout my academic journey, I have developed a deep understanding of subjects including biology, biochemistry, anatomy, physiology, immunology, and neuroscience, and I enjoy helping students build both confidence and mastery in these areas. I scored in the 99th percentile on the MCAT Biology section and have experience breaking down complex concepts into simple, memorable explanations tailored to each student's learning style. In addition to tutoring, I have worked in educational settings including academic mentoring and tutoring, where I learned the importance of patience, encouragement, and individualized teaching strategies. My approach focuses on helping students truly understand material rather than memorize facts. I work to create a supportive learning environment where students feel comfortable asking questions, developing critical thinking skills, and gaining confidence in their abilities. Whether a student needs help preparing for exams, strengthening foundational concepts, or improving study strategies, I aim to make learning engaging and less overwhelming. Beyond academics, I have also contributed to scientific research, including publication work involving peripheral peptides and neuroscience-related topics. My background in medicine and research allows me to connect scientific concepts to real-world applications and clinical relevance. I enjoy working with students at many levels, including middle school, high school, college, and pre-medical students, and I am especially passionate about helping students succeed in the sciences and achieve their long-term goals.

Frequently Asked Questions
This section tests your understanding of cellular biology, biochemistry, molecular biology, and physiology. You'll encounter questions on enzyme kinetics, metabolic pathways, protein synthesis, cell structure and function, genetics, and organ system physiology. The section is designed to assess both your foundational knowledge and your ability to apply biochemical concepts to complex biological scenarios, which requires deeper preparation than typical pre-med coursework.
Score improvement depends on your starting point and study effort, but most students see meaningful gains with focused, personalized instruction. Many students struggle with this section because they haven't connected biochemistry concepts to real biological systems—tutoring helps bridge that gap. Typical improvements range from 2-4 points on the section score, though students who address specific weak areas and commit to consistent practice often see larger gains.
Students often struggle with the sheer volume of biochemical pathways and their interconnections—it's easy to memorize individual reactions without understanding how they fit together. Time management is another major issue; questions require careful reading and multiple steps of reasoning, making it easy to get stuck. Many test-takers also underestimate how much the section tests conceptual application rather than pure recall, which requires a different study approach than general chemistry or biology courses.
Tutors work with you to identify which biochemical pathways and concepts are causing confusion, then build your understanding from the ground up rather than having you memorize disconnected facts. They help you develop efficient strategies for tackling multi-step questions, practice translating complex passages into testable concepts, and create a study schedule that spaces out review of high-yield topics. This targeted approach is especially valuable for this section because success depends on both deep conceptual understanding and strategic test-taking skills.
Practice tests are essential for MCAT preparation because they help you identify weak content areas, build stamina for the full-length exam, and become comfortable with question formats and pacing. For the Biological Sciences section specifically, taking full-length practice tests reveals whether you're struggling with specific topics (like metabolic pathways or genetics) or with test-taking strategy (like time management or passage interpretation). Most students benefit from taking at least 4-6 full-length practice tests before test day, with detailed review of each one.
Most pre-med students spend 3-4 months preparing for the entire MCAT, with the Biological Sciences section requiring consistent attention throughout that period. If you're starting from a weaker foundation in biochemistry or cell biology, you may need additional time to build conceptual understanding before focusing on test-specific strategies. A tutor can help you assess your starting point and create a realistic timeline, ensuring you're allocating enough time to master high-yield topics without burning out.
Look for someone with strong MCAT performance themselves and experience teaching pre-med students through challenging biochemistry and cell biology concepts. They should be able to explain not just what happens in a biochemical pathway, but why it matters and how it connects to other systems—that's what MCAT questions test. Varsity Tutors connects you with expert tutors in St. Louis who understand both the content and the test format, and can tailor their approach to your specific weak areas.
Your first session is typically a diagnostic conversation where a tutor assesses your current understanding of key biochemical concepts, reviews your practice test performance if available, and learns about your timeline and goals. From there, they'll create a personalized study plan that targets your specific weak areas—whether that's metabolic pathways, enzyme kinetics, or test-taking strategy. This foundation ensures your tutoring time is spent on what actually needs work, rather than reviewing material you've already mastered.
