I've received some old GMAT books from some people I've known.
I have some from 98, some from 2000.
Would it be okay to study from these books, or would it hurt me?
I also do have some more recent books (2003-2005) which I have studied as well.
Also, are there any free downloads for practice GMATs besides the crack Gmat and the powerprep? Any other books/software/etc you would recommend? I have Kaplan 800, Kaplan 2003, Arco Master the GMAT CAT, Princeton Review GMAT Math and Verbal Workouts, GMAT for dummies, Arco Unoffical guide to the GMAT CAT.
Oh, and these are the grades I've been getting on my Kaplan tests - what is a good estimate on what I'll get on the real one?
Kaplan Diag: 580
Kaplan Practice: 520, 540, 540 ( :( it's lower)
