Hi mdm4192,
What were your Scaled Scores for the Quant and Verbal sections on each of your practice CATs? And when did you take your last practice CAT?
I usually recommend that no CATs be taken so close to Test Day, as the act of taking a CAT can be a "draining" experience (and I wouldn't want you to be "burned out" before your Official GMAT). You can ultimately assess whether that advice applies to you or not, but I do agree that the weekend should be "light" on study and that you should try to relax a bit.
You might find it useful to re-attempt all of the questions that you got wrong on your CATs because of a silly/little mistake - by that, I mean that you should physically redo the questions (don't just 'look' at them). The act of going through the "steps" and recreating the work on the pad will help you with your 'muscle memory' and you'll be more likely to avoid those mistakes on Test Day.
GMAT assassins aren't born, they're made,
