Hi all,
I m preparing my gmat test .. I tried a couple of online tests(princeton and another one) and I scored around 570-580.
My goal is to get something close to 700.
I was thinking to buy:
1) GMAT official text
2) 8 books manhattan series

Do you think it's enough? (my problems are most on verbal section.. by the way I have a teacher that will help me a little for essays)
