Jeff Sackmann
Jeff Sackmann, the author of GMAT HACKS, The GMAT Math Bible, The GRE Math Bible, and a variety of other resources, has been helping students prepare for the GMAT and apply to business school since 2000.
Until July, 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 hundreds of practice questions), trained teachers, and starred in instructional videos.
Jeff lives in Astoria, Queens, and is currently accepting students for private study. While his business is centered in New York City, he occasionally finds himself in Philadelphia, Washington D.C., and Boston, as well. Phone consultations are available for students who live outside of the northeastern United States.
As you might imagine from a glance at this site, Jeff focuses almost entirely on the GMAT. Despite his experience with a broad range of standardized tests (and other topics), he has spent most of his time since early 2005 on the GMAT. He has taken the test several times, most recently in November '06, when he once again scored in the 99th percentile of both Quantitative and Verbal.
As a tutor, Jeff's top priority is quality over quantity. Rather than exposing clients to masses of concepts and practice questions that they may not remember long enough to apply on test day, he concentrates on building and reinforcing the basic skills that not only allow you to answer more questions correctly, but also help you approach the exam with more confidence.
This technique has proven effective with a broad range of students. Tailored to each individual's situation, it is equally useful for those fresh out of college to those who have spent a decade or more in the workplace. It also applies to any level of skill, whether you are just looking for a little boost to get them over a 700 GMAT score or you are starting from scratch with nary a memory of how to divide a fraction.
