hey,
KSF isn't all that great. I mean if money isn't of much concern to you, then it's not bad because it gives you good practice in doing science questions. But their PAT is aweful, it's nothing like the real thing, and they're orgo is way off. The only thing I could think it's good for is bio, but everything else it kinda sucks. Destroyer is the way to go. That book is genius and should be marked the number 1 study guide to the DAT. I love that book, it's glorious.
