Retaking the test in 5 weeks

that sounds like too many CATs in 34 days. You need time to digest the CATs too, so unless you're not working at all, each CAT takes 2.5 hours to take (without the AWA) and about another hour or two to understand. You listed *26* CATS in what is now 30 or so days left. That hardly gives you time to read up on material and work on problems on the side.

I would highly recommend you NOT take the Princeton Review CATs, as they will HURT you more then help. Their prep materials may be good, but their CATs aren't in my humble opinion. Same goes for Kaplan CATs, but since I haven't taken one of those thanks to the warnings from GMATClub, I cannot be as sure as I am of PR CATs. I know nothing about Crack the GMAT CATs.

I would mix up the CATs and not do all of the same ones. Mix up MGMAT and Crack the GMAT CATs, take one every two days, and throw in PowerPrep 1&2 and GMATPrep 1&2 so that you finish GMATPrep2 a few days before the real test.

I can see you burning yourself out at the end of the 26 CATs, if you actually finish all of them.
