How Often To Take GMAT Practice Exams
Your job is to master the material that appears on the GMAT. Forget about taking too many practice tests until your GMAT prep is nearly complete. Taking further practice tests before you master the material is a poor use of your time. For example, if you have not mastered functions, sequences, probability, and geometry, you can predict–without spending four hours on a full-length practice GMAT–that you probably won’t fare well answering questions involving those concepts.
Instead of using up precious practice exams when they aren’t of the greatest use to you, spend your time training. Continuing to take practice exams without having mastered answering the many types of questions that appear on the GMAT yields little improvement and probably isn’t an effective use of your valuable preparation time.
