Hi shoc064,
Forming a study group could be quite helpful, but you'll still need a proper Study Plan to hit your Score Goal. From your post, it's not clear whether you're just beginning your studies or if you've put in some significant study time already, so if you're interested in any advice for your studies, then it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
