I had my first kaplan diagnostic today. my brain is tired and pained. i don't see how it is humanly possible to take the MCAT now. the diagnostic was a half length exam, and by the end, i was just so tired, i started filling in random bubbles without really reading the question. we also had to take a science diagnostic, and a lot of the time, i would read the question, remember studying it in school, and not remember how to solve it. my fried got so fed up on the last section of the science diag. that she just started filling in c,c,c,c,c,c.... because we couldn't take it anymore. my brain was exhausted, and all i could thing about was how much i wanted to get out of there. i take it as a not so good sign.
