I think yolopolo just did ETS and other couple of free mocks, those who are getting good score with Manhttan mocks should be good to go. To quote him from credit:
15 days before the exam-----
Manhattan Prep Free: Quant-161 and Verbal-159. I was bummed about my quant scores but i felt it was too long and the DI section was crazy (got all 3 wrong) and also made some silly mistakes. Verbal score gave me more confidence
Princeton free: Quant-162 and Verbal-151. Verbal made me cringe but when I went back and analyzed verbal, I came to the conclusion that it was absolutely garbage so didnt bother with the marks. Now I had the confidence to know which questions are potential GRE questions and which ones are not!
I wanted to only concentrate on RCs now as they were my achilles heel. Greprepclub came to the rescue. This is how I strategized. I was able to do TCs and SEs fairly quickly and decided that I should not take more than 8-10 mins for TCs and SEs. This gave me 20 mins for 10 RC questions so 2 mins on average per RC question.
I went ahead and timed my RC passages while practicing on greprepclub (only Old Gre Big Book questions). I realized i was a bit slow. I was confident that I could understand any passage but I wasnt fast and will struggle during the tests. I went ahead and finished around 50 RC passages maintaining the ritual of 2 mins per Q.
