Just concluded my actual GMAT. Got 750
(Q50, V41)
I would recommend all of you to brush up your maths concept well. The questions had a uniform misk, with an added emphasis on number systems and geometry. The first 15 questions were very easy but after that the difficulty level gradually increased and my 27th question took me around 7 minutes

......I had 6 questions remaining with just 10 minutes to go. Obviously I panicked and must have got a number of questions wrong in the last. That's why my advise is to develop a proper time management while taking the GMAT.
The overall difficulty level of verbal section was uniform. I was getting annoyed as I did not get a single bold faced question. The concern that I may be doing a lot of errors kept perturbing me. But when I saw the score, I realized that all these conceren were unfounded. Take the test with a cool head and do not let speculations waver your attention.
My scores in various tests is written below (In case anyone is interested)
Powerprep1 = 690
Powerprep2 = 740
Kaplan 1 = 550
Kaplan2 = 610
Kaplan3 = 660
Kaplan4 = 640
Gmatprep1 = 700 Retook it 770
Gmatprep2 = 700 Retook it 750
Manhattan1 = 550 (Was slightly conctipated

)
Manhattan2 = 660
Manhattan3 = 720
Manhattan4 = 730
Manhattan5 = 780
Manhattan6 = 760 (on the eve of GMAT)
Took a couple of princeton review tests too but found them quite easy.
