I just finished the test a few days ago, and I am glad to be done with it! Here is some background on myself: I am 20 years old (0 years work experience) and am about to enter my third year of undergraduate studies at a top 3 US school. I started preparing for the GMAT by buying the Official Guide that just has practice questions. I did, on average, about an hour a day of review for 4 weeks and then took the exam. On a practice test (with the free software) before any studying, I got 710, and then on two more practice tests (after studying) I got 770 and 730. During the test itself, I ran out of time on the math -- which never happened to me during my practice tests, so I did not answer every question. I do not plan on retaking the test
