Ok, so as of tomorrow I have exactly 18 days left to go. At this point I've "gone through" everything, but I don't feel as if I have "mastered" any one subject. My Qbank scores are totally pathetic, ranging from the mid 50's to the occasional 70. Usually I'm somewhere in the 60's. I really don't want to postpone, and the problem is, that because of some personal committments, even if I do postpone it has to be to the end of July. What kind of a score am I looking at right now and if I study my butt off until the exam what can I get it up to? Is it possible for me to AT LEAST match the mean? What's the best thing I can do from now until the exam to maximize my score as much as possible? Someone help!!!
