Hi NewGuy12,
It's important to remember that a CAT is really a 'measuring device' - when used correctly, it will give you a realistic score and help define your strengths and weaknesses, but it will NOT help you to fix any of those weaknesses. To raise your scores, you have to put in the necessary practice and repetitions. The CAT will show you whether your studies are helping you to improve or not. As such, you really shouldn't take more than 1 FULL CAT per week at the most. Based on what you described, you took FIFTY CATs in 6 months (meaning that you averaged about 2 CATs/week) - and that was far too many CATs for that timeframe.
Since you took so many CATs, it's not practical to think about ALL of those Exams, so I'd like to focus on the last 6 CATs that you took before you took the Official GMAT. When you took those CATs:
1) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
2) Did you take them at home?
3) Did you take them at the same time of day as when you took your Official GMAT?
4) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)?
5) Did you ever take a CAT more than once? Had you seen any of the questions BEFORE (re: in an online forum or in a practice set)?
GMAT assassins aren't born, they're made,
