I have tutored students for the GMAT, GRE, SAT, ACT and LSAT for more than 15 years. I love it! As I tailor my instructions toward the unique needs of each student, my goal is to improve not only the student's performance but also the student's confidence as test day approaches.

I specialize in high-level GMAT diagnostic and execution coaching for stalled high-achievers. I don't just teach content; I identify the execution, timing, and decision-making patterns preventing score improvement and build customized strategies to break through plateaus under time pressure. After years of coaching GMAT students across a wide range of score levels, I've found that many advanced students underperform not because they lack ability, but because they approach questions inefficientlytreating each problem like a new puzzle instead of recognizing recurring execution patterns quickly and systematically. I earned my MBA from Georgetown University and worked as a former Sony engineer, bringing a data-driven and strategic mindset to every session. With 100+ five-star reviews, I've guided GMAT students to break barriersnot just raising scores, but shifting their confidence and thinking. As a result, many of my students have earned admission to elite MBA programs, including UCL
I enjoy helping students by explaining concepts in ways that make sense to them, by eliciting their feedback and tailoring my approach to their individual needs, and by conveying my enthusiasm for the learning process. It's great to see the light come on and to see their progress. I have an undergraduate degree in Politics from Princeton, a post-baccalaureate certificate in Quantitative Studies for Finance from Columbia, and an MBA from London Business School. I served as an officer in the Marine Corps and have worked in a number of academic and private-sector positions. I founded and am currently running an analytics-focused consulting practice.
The GMAT tests two things most prep courses treat separately: quantitative problem-solving and verbal-analytical reasoning. Carl bridges both — his doctoral training at Yale sharpened his ability to dissect arguments and evaluate evidence, while his math tutoring background keeps him fluent in data sufficiency and integrated reasoning problems. He teaches students to read GMAT questions like an examiner writes them.
I have always been driven to share my own passion for learning. While I was in high school, I tutored my peers after school. At college, I continued tutoring, but I also taught a class to middle-schoolers for a semester. Now, professionally, I teach seminars on Government and Politics. I went to Tulane University where I triple majored in Mechanical Engineering, Mathematics, and Philosophy. I tutor STEM topics, government, and test prep. My philosophy of education is that everyone is unique and must have a stimulating educational environment where they can grow. It is my desire to create this type of atmosphere where students can meet their full potential. I will provide a motivating environment where students are encouraged to take risks and strive for success. My teaching style is largely as a facilitator helping students overcome their obstacles.
I enjoy empowering students by making learning fun and believe that everyone has an "inner genius" that just takes the right technique to unlock. I bring a patient and friendly approach to teaching, specializing in the sciences, technology and math, and believe in teaching students to "learn for themselves".
I am an interdisciplinary educator with an Ed.M. from the Harvard Graduate School of Education and a B.A. from Dartmouth College. My background is primarily in integrated arts learning and museum education and I specialize in visual arts, history and art history, and object-based learning. In all subjects, I take a creative, inquiry-based and learner-centered approach, designing opportunities for each unique individual to meet their learning goals.
I'm not tutoring or buried in my textbooks, you will either find me rock climbing at the Triangle Rock Club, playing Ultimate Frisbee, working on my car, or enjoying the great outdoors (beaches, mountains, forests--you name it, I love it). On rainy weekends I enjoy tinkering with computers and old electronics, playing Pokemon, or picking at my guitar.
I am a recent graduate from a masters program in biostatistics at Columbia University. I received my Bachelor of Arts in biological sciences, with a focus in neurobiology at Northwestern University. In August, I will be starting a doctoral program in biostatistics at NYU. I was a teaching assistant at Columbia University in my department and also have tutored graduate students and undergraduates privately as well. My primary areas of tutoring are math and statistics coursework in addition to math sections on standardized tests such as the GRE and GMAT. I am very passionate about helping students feel more confident and excited about math. In my spare time, I enjoy running, playing piano, and spending time with friends and family.
I am a graduate of Wesleyan University, where I received my Bachelor of Arts in Sociology with High Honors. With eight years of experience working in education, I've tutored students in math, science, history, and English, as well as helped students prepare for standardized tests. I've guided adults towards passing the US Citizenship Exam and taught English in India, where I lived for six months. Whenever I work with a student I personalize the lessons to fit their particular learning style, since I know every student is unique and having the right fit can make all the difference in making learning fun and effective. My strengths are tutoring the social sciences and humanities, as well as making math and standardized tests approachable to students that normally don't like those subjects. In my spare time I like traveling, spending time in the outdoors (climbing & backpacking), meditation, and playing soccer. Next fall I will be beginning my PhD in Education at Harvard University.
I am a graduate of Washington University in St Louis, where I received my Bachelor of Arts in History with minors in Humanities and Anthropology. Since graduation, I have worked as a tutor, teacher, and director of tutors at a charter public middle school in Boston. During this time I also received my Masters in Mild to Moderate Disabilities from Simmons College. I have worked extensively with students with a range of abilities, including students with specific learning disabilities, emotional impairments, dyslexia, and ADHD. My teaching experience has given me a deep understanding of the knowledge and habits essential to academic success and has given me the opportunity to hone a variety of strategies that ensure students at each level can achieve their academic goals. While I tutor a broad range of subjects, my favorite ones are Reading, Elementary/Middle School Math, History, and Test Prep. In my experience, tutoring is the most rewarding when a student has that "aha!" moment and achieves a new level of understanding and confidence in his/her abilities. I am a firm believer in the transformative power of education, and I see my role to be that of a facilitator and coach who is there to help the student reach his/her goals through individualized support and rigorous practice. In my free time, I enjoy reading, running, practicing my Spanish, and discovering new music. I am also an avid traveler and just got back from a 3 month trip to South America. I look forward to the opportunity to work with you!

Frequently Asked Questions
Score improvement depends on your starting point and study commitment, but most students see meaningful gains with personalized instruction focused on their weak areas. Many students improve by 50-100+ points by working with a tutor who can identify gaps in reasoning patterns, timing strategies, and section-specific techniques. The key is consistent practice between sessions combined with targeted feedback on the question types that challenge you most.
Your first session focuses on understanding your current strengths and weaknesses through a diagnostic assessment or review of your recent practice tests. The tutor will ask about your target score, business school timeline, and which sections (Quantitative, Verbal, or Analytical Writing) are giving you the most trouble. From there, you'll develop a personalized study plan that breaks down your preparation into manageable milestones leading up to test day.
Pacing is one of the most common GMAT challenges, and tutors help by teaching you to recognize question types quickly, identify when to guess strategically, and allocate time based on difficulty. You'll practice timed sections and learn techniques like skimming, elimination strategies, and when to move on from difficult questions. With guided practice and feedback on your timing patterns, you'll develop the rhythm needed to complete all questions while maintaining accuracy.
Absolutely. Many students connect with tutors to target their weakest section while maintaining their stronger areas independently. Whether you need help with Quantitative reasoning, Verbal comprehension, or Data Insights, personalized instruction lets you drill specific question types and concepts that are holding back your score. This focused approach is especially effective for students who are strong in one area but need concentrated work elsewhere.
Practice tests are essential—they help you understand the test format, build stamina for the 3+ hour exam, and identify patterns in the questions you miss. Tutors typically recommend taking full-length practice tests every 1-2 weeks to track progress and measure improvement. Between practice tests, your tutor will help you analyze which question types and concepts caused mistakes, then target those areas with focused drills and strategy refinement.
Most students benefit from 8-12 weeks of consistent preparation, though timelines vary based on starting score and target goals. Students aiming for top business schools (700+) often need more intensive study than those targeting 650. Your tutor will help create a realistic timeline based on your baseline performance, available study hours per week, and application deadlines—then adjust as you progress through practice tests and targeted skill-building.
Test anxiety often stems from unfamiliarity with question formats or uncertainty about your strategies—both things tutoring directly addresses. By practicing under timed conditions, learning proven techniques, and receiving immediate feedback, you build confidence in your ability to handle difficult questions. Tutors also help you develop a pre-test routine and mental strategies to manage stress on test day, so you can focus on executing what you've practiced.
Look for tutors with strong GMAT scores (typically 700+), business school experience, and a track record of helping students improve. Ideally, your tutor should be familiar with the latest GMAT format changes, understand the reasoning behind correct and incorrect answers, and be able to explain complex concepts clearly. When you connect with Varsity Tutors, we match you with expert tutors who have proven expertise in GMAT preparation and a teaching style that fits your learning needs.
