I don't know where to go from here...

Hi,

My name is Vladimir. I took the GMAT about two weeks ago and scored a 310. I take the torch for the worst on this forum. For the last two weeks i have been torn apart and didn't think i could ever conquer this test. I'm ready now but clueless where to start. I studied for three months 4 to 5 days a week for 4-5 hours a day. While studying i felt like i wasn't learning a thing. I feel the need to take basic algebra, geometry, grammar, etc classes before i even open a gmat book or any online program. I was never great at school but i always busted my a** when i had to learn something and i graduated cum laude. I think i just can't study for a test that i can't go to a textbook to find a solution or have been sitting in a class listening to a lecture for a whole semester. This test made me feel like i haven't learned a thing my whole life. I graduated two years ago from college and have completely lost my studying habits and especially knowledge on courses that would help with this test. Is there anyone out there that has gone through this please help. My goal is 500-550.
