Looking for a more personal approach to preparing for the GRE Math Subject Test? I have offered GRE tutoring since 2015, during which I have helped prospective graduate students raise their scores by as much as 20 percentile points. I tutor via Skype, so I can accomodate students wherever they are. During a tutoring session, we can refresh skills from undergraduate mathematics courses, break down practice test questions, and discuss test-taking tips to manage your time and neat tricks to answer tough questions more quickly.

Testimonials

“I thank Bill tremendously for his role in my performance increase on the mGRE. It had been a while since I touched Calculus and our sessions were helpful in reviewing many topics I learned years ago as well as the intuition behind the ideas. Bill also taught my very useful tricks for calculations that allowed me to quickly move through the exam on test day. He also provided me concise outlines of commonly tested topics that allowed me to effectively prepare for the exam. Thank you Bill. “

C.M. — 830 (82nd percentile)

“Bill’s session definitely helped me; first of all, it’s valuable to get another perspective when you’re working in isolation, and opportunities to hear from someone who has an ongoing engagement with (and understanding of) the test are extremely rare. Second, in a short amount of time, Bill gave a powerful overview of which materials were actually helpful to study from, and perhaps most importantly, a down-to-earth map of which concepts appear most often on the test, along with specific types of problems and mathematical objects that I should expect to see. All of this provided valuable direction to the rest of my studying.”

C.M. — 800 (78th percentile)

I prepared for the exam on my own last year and got a score of 800 (77%). It’s a decent score in principle, but is still below my own expectation of scoring a 85%+. I have reviewed all the things on the Princeton review book, did all the practice exams, but there are always gaps between the book/practice exams and the actual exam (I don’t know what to do about it). Bill’s tutoring sessions helped me overcome these gaps. Bill made his own practice problems which closely approximate current exams. Working out these problems every week efficiently covers my blind spots,  especially on advanced topics such as real analysis and topology. Moreover, Bill’s emphasis on examples and counterexamples is a good test-taking strategy, and makes me realize that the exam is not as intimidating as it appears to be. Though the subject exam is cancelled in 2020, I’ve definitely improved thanks to Bill’s great tutoring. I also had a good review of my undergraduate curriculum in the summer, which will benefit me in the long run.

It had been at least a year and a half since I did computational math like calculus and linear algebra, and I had altogether skipped any kind of course on discrete math (counting/probability), Bill’s experience with tutoring helped me to structure my studying so as not to waste any time and instead work directly where I was behind. He also offered a host of practice problems and practice exams, which as I’m sure you know are difficult to find all in one place. Working through them together offered me insight into problem solving strategies which are of key importance to solve problems under time pressure. Regardless off your background, Bill’s expertise will streamline your studying for the GRE so that exam problems no longer seem as daunting or involved come test day.

Bill is the only tutor out there who has turned the vague ETS test description into a concrete list of specific, studyable topics. By reviewing practice questions with Bill, I saw how he solved questions using counterexamples, figures, and intuitive shortcuts. Studying for the mGRE is a lot of work, but with Bill’s help and enthusiasm for math I found that it was also an avenue for learning a ton of cool mathematics. Bill is a fantastic teacher and I highly recommend him to anyone taking the mGRE. Thanks!

Once you talk to Bill, it’s quickly apparent that he is intimately familiar with the math subject GRE. He possesses an abundance of helpful calculation tricks which help turn 4 minute problems into more tenable 2 minute ones. Bill also helped point me in the direction of what material it is best to focus on and is higher priority, and what topics are less important. He could explain any concept I wasn’t familiar with quickly, clearly, and effectively.

Bill made it very convenient for me to quickly go over topics for the mGRE. He provided a thorough practice of important problems along with several unique time-saving tricks! I definitely recommend Bill to anyone who wants to prepare well for the exam.
