There are many resources available online which helps you to prepare SAS on your own.

Free SAS Tutorials: SAS Tutorials | SAS Training

SAS Books: Welcome to Books The little SAS book,  Programming with base SAS

(As far as I know, you get a 20% discount on these books if you are SAS certified)

SAS Training: Courses and e-Learning from the experts at SAS

(The in-class training is a bit costly and would be better if your organization sponsor it, as they get group discounts)
