So, as far as I know, there are three SAT(I) books from Collegeboard:

Official SAT Study Guide Second Edition
Official SAT Study Guide First Edition
10 Real SATs
(I’ve seen the latter two can be bought on the Internet)

Is there a difference between the first and second editions (tests wise)?
Is 10RS relevant for SATs now? I know that came out before the change in 2005, so I was just curious if I should get it.
Right now I have the 2nd Edition and I’m almost done with it…

Supposedly you can buy past PSATs, but I can’t seem to find them on CB’s website- did they discontinue this, or am I terrible at searching?
