GMAT Strategy

Can I take GMAT prep CATs more than once/
Do a lot of Qs repeat themselves?

Yes you can do that. But you will see a lot of repeat questions. Your test score may be skewed once you start repeating the tests. But for the sake of practice, it's a good thing.

How realistic is the Princeteon free test?
I am a week away from my GMAT
I have 1 MGMT and 1 GMAT CAT, looking for one more - dont want to do Knewton anymore and my Kaplan CS is broken

I would suggest you to practice more with GMATPrep first since you are just a week away. Keep in mind that you don't exhaust yourself before the exam. People normally recommend not to study in the last 2 days and just review your flashcards and read few passages to get into the mode.

Princeton review test - I felt that their math is too easy and verbal is alright. Their scoring is horrible in my opinion, like Kaplan tests . When you take this test, you should not consider the score but rather you should look at how you have performed and analyze all questions.

I took the GMATPrep 1 twice, but came across only a couple of problems that I had encountered earlier. It's definitely worth taking twice.
