when i took the exam in august . . . i didnt start studing until i believe end of june . . . but im not positive . . . but what i did to prepare for it was to just take TONS AND TONS of practice exams . . . during the week i believed that i took 3 full length practice exams . . . and studied what i got wrong . . . if you are taking one of those course review class . . . i would recommend, if youre not doing anything else this summer because otherwise itwould be hard, to just finish that in a month if possible or sooner since summer is only three months . . . and take tons of practice tests and study what you got wrong . . . i also recommend on top of that to do two verbal passages a day . . . with this i can probably almost guarantee you a score above a 30 . . . it worked for me . . . my girlfriend who scored a 36 and her kaplan diag was a 21 . . . and another friend of mine . . . well good luck studying . . . oh and i heard that the format changed for the august mcat . . something about verbal being at the end and less questions on the exam as a whole . . im not to sure about that but u should probably check with one of those course review centers .. . alright . . . good luck!
