Hi Guyz ,
gave my GRE on 3rd, with a pathetic score in Verbal-310.....
I gave Quants offhands.....Let me share my expereince with you...

Quants-
I just went the through questions , with celerity...those were quite easy to solve....in many of them i even did'nt find it to solve them....I just looked at them and made choices...that's it....and in the last 2 mins I was left with 6 questions....I just clicked and moved.....without even looking into the questions....
and landed upto 750 only...

Verbal -
The biggest mistake made by me was not to practice the RC's , Sentences,Analogies.....I just went throught the wordlists....and even not completely.....Went through the words(around 2000).....
The main technique to crack is to keep your head cool...like i did'nt do
otherwise time will pace like a Bullet, and you would miss the questions like I did in Verbal part also...guessed around 10 questions(in the last 5 minutes)...
that was just because i did'nt gave sufficient time for practicing RC's,sentences and Analogies.....

In a time span of 25 days ..i gave my GRE....
Now going to give another one in September/October......

I hope my experience will help you guyz....

Best regards
Sandeep
