GMAT Impact: Mastering Official Guide Sentence Correction Problems

With regard to the GMAT, raw intellectual horsepower helps, but it is not everything. In this weekly blog series, Manhattan GMAT’s Stacey Koprince teaches you how to perform at your best on test day by using some common sense.

Are you struggling to improve your Sentence Correction (SC) performance? Do you love studying official problems but hate trying to decipher the sometimes mystifying official explanations? Do you want to throw your Official Guide for GMAT Review, 13th Edition (OG13), across the room when you read yet another explanation that says an answer choice is “wordy” or “awkward”?

Manhattan Prep’s book The Official Guide Companion for Sentence Correction (OGSC) contains, among other things, our own explanations for every single one of the 159 SC problems contained in the OG13.

If something is “awkward,” there is a real reason why—and we explain that specific reason to you so that you can start to pick out similar faulty constructions in other problems in the future. (Did you know that most of the time, “wordy” and “awkward” are code words for an ambiguous or illogical meaning? The OGSC will help you learn to decipher these for yourself!)

We also tell you the SC process for getting through any SC question efficiently and effectively. We discuss how to eliminate each wrong answer in terms that are easy for students (not just teachers) to understand. The book also includes an extra section on sentence structure and a glossary of common grammar terms.

In addition, OG Archer, our Official Guide study companion program, now contains all these explanations. If you already have access to OG Archer, you can view these explanations immediately. (If you are in one of our study programs, including our nine-week classes, tutoring or guided self-study programs, then you already have access to Archer. If you have never used it, start today!)

If you want to get a hard copy of the book, it is available on our site and on Amazon.
