I'm asking this because I'm debating whether buy 6 prep books is economical? I know 60 is meager compared to what I might spent in college. But I already regreat buying so much SAT material the last 2 years and like 2 shelves are all my SAT books. My library has a lot of barron AP books, but you can't write on it (duh. xD). So is there a substantial difference or not?
p.s. I'm taking these classes so maybe you can give me more tips and quirks and whatnot? It would be so amazing!
