Shoot for the moon. Even if you miss, you'll land among the stars

A common denominator among 700+ scorers, these tests provide you with the 'next level' quant training necessary to properly perform on test day. I have used them exclusively in order to prepare for quant, so I cannot comment on their effectiveness in verbal.

Make no mistake, they are much harder than the real thing. Nevertheless, they give you that extra confidence boost when you know that the actual test won't be as bad. The CAT interface is designed to look very similar to the actual test. The question bank is large, varied, and has a high number of 700+ questions. After going through the OG and learning all the fundamentals, I highly recommend plowing through as many GMAT Club tests as possible in order to build pattern recognition and quick reflexes. Some of the questions will be challenging, so try using practice mode in order to have a proper attempt.

In my opinion, these tests are the most efficient method of using your time if you want to jump from a Q42-47 to a Q48+. Thank you Bunnuel and GMAT Club for such a valuable resource.
