I took my GMAT test recently. It is to my utter surprise with my score 590 (Q -50 , V- 23)

. In my preparation test of GMATPrep 1 (670) and GMATPrep 2 (660) I have done decent score. This one was my first attempt and I have completely lost my confidence after that. I have prepared OG , Kaplan, Princeton and 1000 series extensively still I had this horrible performance in verble section ... please I need your help to improve my verble section and to gain confidence so that I can at least score around 700 in my next attemt which I am thinking to write in september'08. Frankly speaking I did not find verble section too tough in my first attempt , I find it simpler than quant section . So I have lost my full confidence in my own answer choice in verble section
thanks,
