New GRE Study Approach for 30 Credits (12LL, 18UL)

[steelers]

I scored a 590 on the GRE Psychology exam (earned 9LL credits) a year ago studying for only 3 weeks. I used only the Princeton Review "Cracking the GRE Psychology". Now that all of these Psychology cards are available I'm wondering if the Princeton Review book (very concise), plus studying ALL of the IC LL and UL Psychology cards would be enough to score in the 80th percentile. Somebody needs to try it. Imagine 30credits (12LL, 18UL) on one exam!!! Also, imagine how much money would be saved. I think the exam cost was only $150!
