Hello All,
I took my GMAT in May and got a dismal 510 Q32 V28 AWA 4.5. I was heartbroken; I didn't sleep well, didn't eat breakfast, got to my test center late and I think everything just frustrated me before I even had a chance

. I ran out of time on almost all of my sections and left feeling really down. I'm a bookworm, I couldn't even believe I received such a HORRIBLE verbal score, I was depressed for two days about my GMAT score. However, I've decided to try again until I achieve my target score.
I want to get into Top 10 schools, my target score is 700+. I used
MGMAT (foundations of math and the 8 strategy guide set) books to prepare for the test as well as the OG 12.
I know that I need to up my quant score (data suffiency is my main problem) but I was kind of relying on getting an incredible verbal score to balance it out.
What should I do get a higher score on my next attempt?
I've decided that I may need a to enroll in a test prep class.
I'm debating between
MGMAT and Kaplan. Any advice is duly appreciated.
