Hi till now i have given 3 GMAT practice tests and analysis are as below:
GMAT PREP1
quantz-44
verbal-24
total-560
today i had just given the GMATPREP practice test, i think i had improved somewhat and below is the analysis:
GMAT PREP2
Quantz-47
Verbal-31
Total-640
MGMAT free test
Verbal-21
Quantz-44
Total-540
Please suggest me how to improve my score. i have my GMAT exam next week. When i practice the verbal section i score fairly in the 600-700 range. But today when i gave the whole length test, i scored 540, which is very less.When i reached the mid of quantz section i was feeling sleepy,(so finished the quantz section with 5 minutes remaining and verbal with 15 minutes remaining) so was just about to think of finishing the test. Please suggest suitable measures to be taken. Less time

I am totally confused.A week to go.And with these scores i dont know where i stand.
Please HELP.
