The Importance of Getting to No on the GMAT — Part 2

by

Last time, we talked about how crucial it is to develop the instinct to go for the “No” when taking the GMAT. If you haven’t read the first installment, do so right now, then come back here to learn more.

I left you with this GMATPrep® problem from the free exams.

“*If 0 <r< 1 <s< 2, which of the following must be less than 1? “I. r/s

“II. rs

“III. sr

“(A) I only

“(B) II only

“(C) III only

“(D) I and II

“(E) I and III”

Let’s talk about it now!

Manhattan Prep secures endorsement from Dr. Lawrence Rudner, leading GMAT authority

by

Larry Explains 2I have some very exciting news to announce.

For the past several months, we have engaged Dr. Lawrence Rudner, former Chief Psychometrician of the Graduate Management Admissions Council (GMAC, the makers of the GMAT®), to review our practice tests. Dr. Rudner is one of the world’s leading experts in item response theory, the testing principle on which the GMAT is based. He is the definitive authority on the GMAT examination.

And here’s what he has to say about Manhattan Prep’s practice exams:

“I conducted an extensive examination of student data for all of the Manhattan Prep test questions and I was very impressed. I can attest to the fact that very high percentages of Quant and Verbal items have excellent psychometric properties. I can further attest that Manhattan Prep’s GMAT practice exams do an excellent job of predicting a student’s score on the actual GMAT examination. Manhattan Prep’s GMAT practice exams can help you accurately gauge when you’re ready to achieve your goal score on the real test.”

Lawrence M. Rudner, PhD, MBA

In short, our tests do “an excellent job of predicting” your score on the real GMAT. That’s great news!

I am particularly excited about the fact that our CATs were so strong that Dr. Rudner offered his endorsement without requiring us to change a single thing. Going into the review, we had thought that we would be given a required list of changes before he could give his seal of approval.

I do have to add a caveat: nothing is perfect and not everyone scores on the real test exactly what they scored on our test (or any practice test). No standardized test is that precise, including the real GMAT. There are also other factors that can negatively affect certain students, such as anxiety (you know your practice tests don’t really count) or mental fatigue (don’t study for 6 hours the day before the real exam!).

Caveat over. In general, you can trust our exams to help you know when you’re ready to get in there and take the real thing. I already felt that way before, but now I can say it with conviction, because Dr. Rudner has confirmed the accuracy of our exams.

I have to give a shout-out to all of our instructors who have worked so diligently on our exams over the years—you know who you are. We literally would not be having this conversation right now if not for your hard work and dedication to making our materials the best. Thank you for your love of teaching and your complete fascination with the GMAT. I’m proud to call you colleagues and friends.

And back to our students: Go forth and study! You can beat this test!
