I will be taking the GRE at the end of the month and I have spent about a month studying so far. My roommates who have taken the GMAT have told me that I would be better off taking a bunch of practice tests under test conditions and spend less studying and using the prep books. I've seen people do extremely well using the exact opposite approach( 1 or two practice tests). I've taken only 2 practice tests in my month of studying, and I study about 10-12 hours a week. This will be my first time taking the exam. I'm feeling pretty good about the verbal section and a bit nervous about the math. Which approach should I use to prepare for my exam(in 20 days)? Thanks guys!
