GMAT Ninja Quant Ep 8: Number Properties I: Methods & Mechanics

Do you get lost in the “word soup” of GMAT or Executive Assessment number properties questions? Do you some methods for tackling number properties questions, but you're not sure why those methods don't always work?

In this video, Harry -- a GMAT Ninja tutor -- will help you identify which number properties questions can be solved using a methodical, technical approach. Among other things, he'll show you how to use "quasi-algebra" to answer these questions efficiently under time pressure.

This video covers a wide range of difficulty levels. It starts with some simple questions to cover the foundations of GMAT and EA number properties questions, and the difficulty level builds through the rest of the video. This video finishes with a very tough question that will challenge nearly any GMAT or EA test-taker.
