For those who scored above 20 and used the Topscore CD, did you see any trends/similarities in questions on the real DAT? I've heard that some questions actually reappear on the real DAT. Is this true? Also to those who did exceptionally well in the Gen Chem & QR sections, what was your most effective study technique/guide. The calculations & stoichiometry questions is what really lower my score. Please help as I only have one more week before my DAT exam. Thanks!
