I just used the Kaplan book and read over it once taking notes. Then i took a practice test and got 760 so I read over some of the chapters again, took two more practice tests, got 800 on both.
Took 3 days for me, but I already knew everything that was on the test already.. just needed to brush up on some old stuff.
I can't really comment on any of the other books (
PR, Barrons, etc..) b/c I haven't had a look at them.
