GRE Tutors, Events, and Resources

Hello! I’m Rouhin, a highly experienced GRE tutor with over a decade of proven success helping students achieve top results. I’ve earned perfect scores on the SAT, SAT Math II, GRE Quant, GMAT Quant, and ACT Math, and I’ve guided students in reaching their own top scores — including perfect scores — across GRE Quant and GMAT Quant. What sets me apart is not just mastery of the material, but the ability to teach it in a way that clicks. I tailor my approach to each student’s learning style, breaking down complex concepts into clear, manageable steps and building both skill and confidence along the way. I’m excited to work with you and help you reach the GRE Quant score you’re aiming for!

Whether you need help with quantitative reasoning or verbal skills, I'm here to guide you every step of the way. My score was able to get me admitted to both Harvard Business School and Stanford's Graduate School of Business. Let's connect and create a personalized plan to boost your GRE performance!

Carl has taught, literally, thousands of students to succeed on the GRE, and thousands more the ACT, SAT, LSAT, and GMAT, over a career spanning over two decades in the test preparation world. Originally an academic, he holds advanced degrees from Yale, the University of Glasgow, and the University of Georgia, and since leaving academia he has taught, tutored, and written content for Magoosh, Kaplan, Harvard Prep, SuccessPrep, Parliament Tutors, Varsity Tutors, and many other companies, and has since founded his own company, Ivory Tower Tutoring. He was also, for many years, the chief writer for Barron''s GMAT product line.

Clients preparing for the GRE are generally motivated and ready to work hard to attain their desired score. Where I come in as a coach is not only with subject matter knowledge, but the ability to help you focus your preparation and make the best use of your time. I'll also teach you strategies specific to the test—the way questions are worded and the way passages are structured can often give you important clues once you know what to look for. Furthermore, I have many years of experience as a classroom teacher and tutor, especially in math. I am able to draw on those other experiences to help GRE students by suggesting other resources to shore up particular areas that need work. Many of my GRE students have strengthened their mathematical problem-solving ability by going outside the bounds of GRE prep books; they were then able to apply these skills to the actual GRE.

I had a lot of test anxiety building up to the GRE exam date. As such, I knew I needed extra help to not only learn the test but to be mentally prepared for it. I developed a holistic approach that includes lifestyle changes that helped me perform beyond my target score. I am excited to share these unique and non-traditional tips and tricks with you.

As a former SAT/ACT Tutor with Prep For Success, I designed personalized lesson plans that significantly improved students' test scores and college readiness. I have taken the GRE twice with large improvement in the second score. Whether you're aiming to boost your quantitative or verbal scores, I'm here to guide you every step of the way.

I am a current Harvard Business School student who received admissions to 4 top-rated MBA programs and received $450k+ in merit-based scholarships. I took the GRE and would be thrilled to share the strategies I learned to nail the test. I support applicants across the Verbal, Quantitative, and Writing sections of the test with tried and true methods. Together, we can generate a game plan, work through time management, designate your problem strategies, and master practice sets.

As a university mathematics professor with over 14 years of teaching experience, I bring deep analytical rigor and structured problem-solving expertise to GRE preparation. My academic background allows me to break down quantitative concepts clearly and efficiently, helping students strengthen both their foundational skills and their strategic approach. The GRE is not just about knowing math formulas, it’s about recognizing patterns, avoiding traps, managing time, and making disciplined decisions under pressure. Because of my experience solving and teaching complex mathematical problems, I’m able to train students to think systematically and approach questions with clarity and confidence. I’ve worked with students from diverse academic backgrounds — including engineering, economics, business, and the humanities — helping them improve not only their Quant scores but also their overall reasoning skills. My goal is simple: transform the GRE from an intimidating exam into a structured challenge that you can approach with control, precision, and strategy.
