Jeff Sackmann


Jeff SackmannJeff Sackmann, the author of GMAT HACKS, Total GMAT Math, Total GMAT Verbal, Total GRE Math, and a variety of other resources, has been helping students prepare for the GMAT and apply to business school since 2000.

Until 2005, he worked for one of the large test-prep companies, teaching classroom courses, running workshops, and tutoring. He has also taught the LSAT, GRE, SAT, and countless other specialized admissions and certification exams. In addition to teaching, he has written curriculum (including thousands of practice questions), trained teachers, and starred in instructional videos.

Despite Jeff's experience with a broad range of standardized tests (and other topics), he has spent most of his time since 2005 on the GMAT, an exam he has taken several times, scoring in the 99th percentile on each administration.

In his books, Jeff focuses two things: building solid content knowledge and providing extremely realistic practice material. Unlike many other resources on the market, his practice problems are virtually indistinguishable from the real thing, making you that much more prepared for the GMAT before you sit for the exam.
