Thanks Fiver.
But after analyzing a little more yesterday, now i think i over worked myself in the last week. I took GMAT 800 test on previous saturday, 3 paper tests - sunday, monday and tuesday. GMAT Prep 1 on thrusday, Prep 2 - Saturday and the real GMAT on monday.
I guess all this just screwed me up and kept playing on my mind. [

]. One and half to 2 weeks before the test, i was gung-ho as i thought my prep was good. Started seeing improved scores on tests - thats when i scored 750 in the PowerPrep.
Then lost it doing the paper tests and other tests in the last week.
Hmm, i cant go back now.
So any suggestions on when i should be taking the test again? And what books i should refer? (I referred to OG10 and 11 for this test)
