I have 10 days left and yesterday after 2 months of preperation I gave my second GMAT prep test. I am still scored a 630 and then re-tried and got a 660. I manage to get a good score in the quant section (between 40-4, however my verbal score has never gone beyond 28.

I am worried as I make a lot of silly mistakes in CR and SC. I really dont know what to do with only 10 days left. My target score is anything above 680. Please can anyone suggest if GMAT prep score is a reflection of my final score?
