You can at least go throw destroyer once in that time. You can learn everything on GC and Organic in about a week with destroyer. And if you know everything for those subjects from destroyer, you will most likely get 20+ if you know the basic content. I took DAT twice and got mid 20s on GC and Orgo BOTH times and thought destroyer was the best source for those subjects. I am selling a 2008 destroyer cheaper than the retail at http://forums.studentdoctor.net/showthread.php?t=655448
