Often, confusion exists about the uses and benefits of practice tests, and the role of practice tests in preparing for the GMAT. Let’s try and offer some clarity to the situation:
Practice tests are evaluative tools and should be used as such. They are NOT learning tools. You use tests to asses what you have learned and your ability to apply that learning under conditions as similar to the real exam as you can make them. As such you should only be taking practice tests at most once per week (unless you are not working), and should seek to simulate the conditions of the actual test as much as possible when doing so (especially in the last few weeks before the real exam). In the larger preparation picture, you should take a practice test at the very beginning of your preparations to establish a baseline and determine your areas of strength and weakness. After that, it would be advisable to hold off on doing another practice test until you’ve had a chance to do some content review and focused, small-scale practice. Once you’ve gotten a sizable chunk of material and practice behind you, you should start incorporating full-length practice tests into your preparation regiment.
