GMAT Tutors, Events, and Resources

Carl has taught, literally, thousands of students to succeed on the GMAT, and thousands more the ACT, SAT, GRE, and LSAT, 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.

The GMAT is a fascinating test compared to others I have coached for (SAT, MCAT, USMLE, etc) if for no other reason than because of its unique scoring and administration system. The GMAT is also differentiate from other professional school exams in that test takers are working professionals applying to business school in parallel with full-time work (as opposed to students with more flexible schedules) and the exam tests topics that most examinees have not directly used in years (think: geometry, multivariable algebra, etc). Each of these features add a dimension to the learning curve which can either make the exam especially challenging OR can be leveraged to accelerate score improvement relative to other examinees. When I coach GMAT clients, we focus on the HOW more than the what. Specifically: how to prepare for the test (what to do each day of prep) and how to take the test (what to do when at the computer on exam day). Focused review of specific content can also be useful on a case by case basis for topics that are particularly problematic for the client and also highly represented on the exam.

I spent a VERY long time studying the GMAT only to come up very short on GMAT math. Twice. Then I spent weeks doing nothing but studying those who ACED the exam, with an emphasis on those who did so after having middling scores. The result was a big change in my study and practice process. And I went from 54th percentile math scores TWICE after lots and lots of study, to getting the effective high score on the GMAT Math after only a couple months of study with my new process. I will show you exactly how I did it so you have the same framework and standards I had.
