Hi IKR9,
With a planned Test Date at the end of April, you have about 3 months of potential study time - which is good. That having been said, you cannot afford to continue studying "off and on" - to hit your Score Goal, you're going to have to commit to a more consistent study routine.
I'd like to know a bit more about how you took your CATs:
1) On what dates did you take each of your CATs and how did you score on each - including the Quant and Verbal Scaled Scores for EACH?
2) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
3) Did you take them at home?
4) Did you take them at the same time of day as when you plan to take your Official GMAT?
5) 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.)?
6) 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,
