I've been studying hard for 6 days a week since June 1. I've read Kaplan, Cliffs, watched all of Chads gchem videos, and done destroyer through 2 times. I've taken the Kaplan CD and Kaplan book test and done pretty well. I am taking a topscore tomorrow to see where I stand with that. It is getting hard to study, I feel like I am just wasting my time now because I can't concentrate like when I first started studying. My test date is August 13th, should I push my date up to maybe July 31st or something?
