I used Kaplan's Premier GRE 2016 book/software (provided by a research program I did over the summer). Did practice problems out of the book and took one computer-based practice test through this software. Practice test score: 167 Q / 159 V (QVQVQ) Actual score (3 October): 168 Q / 165 V / ¿AWA? (VQVQV) Hours studied: ≤20 (I was spending 6 to 12 hrs/day for 5 weeks on the Physics GRE, so I neglected to pay much attention to the General) Observations: Taking at least one practice exam of the type you'll see on exam day (computer or paper based), especially for someone preoccupied with studying for subject tests (e.g. math and/or physics, where the subject is much more important than the general), is crucial. This may seem obvious, but I have friends who have tried to take it cold because they couldn't find authentic practice exams. Understand that, assuming you're 1) taking the computer-based and 2) aiming for a high score, your second half of the exam will be hard! I actually took a bit of a mental break on my experimental section because it noticeably easier. If that was my actual second verbal section, then my score would have been too low to report anyway. Sure enough, a harder verbal came in the 6th section and I knew it was genuine and to focus on it. Math questions in study books ≠ math questions on 2nd half of the GRE (for anyone in the ~165+ range, that is). This was the biggest thing the practice test taught me. I took a few paper-based practice sets out of the Kaplan book and would get 39/40 or 40/40 in roughly 1/2 or 3/4 of the allowed time. Your test day experience will be very different from these practice sets if you're shooting for a perfect quant, and you need to be mentally prepared for this. (I gave myself a little mental pep talk before the 2nd math section of my actual exam, because I knew this section would be challenging.)This might be a matter of personal preference, but take all the allotted time on a given section! If you finish answering and checking your answers with ≤5 minutes left (e.g. on the first quant and verbal sections), don't skip the remaining time. If you're sure of your answers, take a break and just relax. I was one of the last people done when I took the exam, presumably because everyone else rushed through. I don't know why you would willingly force a brisker pace upon yourself – if anything, use the remaining time to review the questions a second or third or fourth time, rather than forfeiting it. Takeaways: Second-half quant questions for top-end scorers are much harder than questions I found in review books or online.Knowing what difficulty your second-half questions will be will help you spot (and take advantage of) the experimental.
