I can not believe you guys. You are

. You guys replied. I am already feeling better.
Here are more information->
1. My timing is way off. most of time I run out of the time in the end ( around at q 34 at math and 36 at verbal). I thought I am good in math, but I am not doing good either in math or in verbal.
2. After I do test, I analyse it why I did it wrong and create error logs too.
3. Materials -
Kaplan books
Princeton verbal book
All 7 ManhathanGMAT book
kaptest online quiz bank
OG10
4. I have been studing 25 hours a week.
5. What I feel that I am not able to comprehend question quick enough to answer in a limited time, therefore I either make silly mistake or do it wrong.
6. I gave 3 kaplan test and consistently got around 550 score. I also gave manhathanGMAT test, I got 550 too. I have roughly same number of wrong answers in all subcategories, so I know it is not one subcategory I have to focus, the problem seems to be sou enough something else.
Please let me know your view.
