Kaplan book 2003 vs. newest version?

[khoius]

I have Kaplan books 2003 and now I want to ressume study for step 1. My question are:
- What is the newest version of Kaplan books? Do I need to buy the newest Kaplan books or should I study 2003 version which is easier for me(because I did study those books)? Any differences?
- There are any new study aides recently beside FA, Gojlian 200? , BSS?
Thank you for any reply.
