At my house, there are two SAT practice test books just lying around. They are:
Kaplan 2007 12 Practice Tests for the SAT
Princeton Review 2011 11 Practice Tests for the SAT and PSAT
I have heard that there are a lot of errors in these books.
In addition to the CB blue book, I'm going to be using these books above ^ as extra practice. Can anyone tell me the magnitude to which the errors are present? I just want some extra practice. Also does anyone have a link or anything like that that has found every error in these books and corrected it?
