Excellent addition to a set of great books

As many other reviews have articulated, the gold standard for predictive testing are the GMAC tests available through GMATPREP, and while I do agree with this, I also believe these tests can be a great addition to any study plan.

Specifically, I think these tests can be used to supplement relaxed study, and to build stamina before test day. I used these tests between reviewing topics, and doing problem sets of between 5 and 15 questions at a time. It really is more challenging initially to stay focused throughout the entire duration, however the more you do these tests, the better prepared you will be to keep up the speed.

On the negative side, I don`t believe the quant section effectively mimics the question style I have seen in the OG books. This is a personal opinion, of course, but it did not impair my enjoyment of the software because I used these tests less for their predictive capability, and more so for building test stamina.
