Help! I have been doing practice exams and my scores have been in the range of 600-680, but when it came to the real thing I got 530. I've been using the OG workbooks and Kaplan ones but it seems my scores are getting worse rather than improving..... Mainly it is my Quant score which seems to be getting worse. I really need to get at least a 650 which is the conditional offer my course has given me. Advice on study guides/material anything!
