Performing mental math calculations faster and more accurately is a surprisingly important element of success on the GMAT.  And for any given ability level, It’s also important to gain confidence in your mental math abilities before taking the GMAT.

Although you’ll likely see slightly fewer Critical Reasoning questions than Sentence Correction or Reading Comprehension on the Verbal section of the GMAT, it is still a sizeable portion of the exam. Having a strong foundational knowledge of argumentation is key to understanding how to answer GMAT critical reasoning questions correctly.

The way the Official Guide to the GMAT, and too many GMAT tutors for that matter, explains how to answer GMAT sentence correction questions is overly confusing. The explanations are far too technical. You are taking the GMAT to get into an MBA program. The MBA programs wants to ensure you can read, write, and speak English well. Neither you nor the MBA program should be concerned with PhD level technical elements of the English language. In this article we’ll teach you how to correctly answer GMAT sentence correction questions by following a four-step process.
