Thank you, Orst!
That makes sense - I am a "decent" test taker. I'll be applying to the Masters in Public Health (MPH) programs. A school coordinator told me that as far as the score needed, no one really knows because of the new GRE exam. They'll know by November of what the minimum requirement is. I feel that I have given me enough time to study all 3 books. It's better to be safe than sorry, and I rather cover as much as I can. I just always hear about people buying one or two books. I didn't know if I was wasting money!
