MCAT diagnostic score!

I just took a free MCAT practice test from Kaplan and scored a 492 Chem/Phys: 124 CARS: 123 Bio/Biochem: 122 Psych/Soc: 123 I haven't started studying for the MCAT at all, and i plan to start next week. This score is horrible and it really scares me, how worried should I be? I want to score 517-520, is that possible? I plan on taking the real test in April or May. What did you guys score on your diagnostic vs your real test? THANKS in advance!
