1) when i first read your username, i thought it said "slaframine" (aka slobbers disease of sheep

)
2) i think if you can swing it, you should find out from upperclassmen AT LSU what books are recommended and useful. SGU recommends and "requires" an enormous amount of books. thing is, most of them never get opened because either our notes are sufficient, the professor has office hours to explain stuff, or the golden web helps us out. we may or may not have quite a few pdfs circulating around our student body too...point is, find out if people who went through those classes think you need the books. would certainly stink to pay money for something you never open!
