I think it really depends what you've been doing since college. If you still do a lot of critical thinking, writing, math, etc, then you're in a better position as far as studying goes...but if that hasn't been your life, I would say more studying and/or reviewing would help. Also, do you read alot? I was always told that to prepare for grad school, it is one of the best things you can do...read, read, read...anything! Newspaper, novels, anything. I took the GRE right after college so I was in "school" mode, but if it's been a while, you need to prepare your brain to think like that again, you know? I used the Kaplan study book and that helped me alot at that point and I really didn't actively study very much, I read through the book and did the practice problems but that was about it. I think the biggest help will be getting yourself back into the right mindset...maybe take a class (even an online class)while you are preparing... to get yourself back into that critical thinking frame of mind...Also, what was your undergrad degree??? that might tell you where to focus your studying...if your undergrad was english based you might just need to review those type of sections on the GRE studying while focusing more on learning the math...overall, i think the pretests most of the books offer are a good tool for gauging what and how much to study...also, maybe a GRE prep course might help...If you don't have time for an actual class, maybe an online prep course. If anything something like that can boost your confidence which, really, is half the battle sometimes. Good Luck!
