Hi Mr.Boomerang64,
From the information that you have provided so far, and considering a Score Goal of 650+, I think that a May 21st Test Date would be too soon (so the June 11th Test Date is the far more realistic one for your Goals). Obviously, you will have to learn and hone some specific skills before you will be able to consistently score 650+, but the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level.
Before I can offer you the specific advice that you’re looking for, it would help if you could provide a bit more information on how you've been studying and your goals:
1) What type of study routine have you been following? How many hours do you typically study each week?
2) Have you used any other study materials besides the course that you mentioned? What “brands” of CATs/mocks have you used?
3) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
