Hi myself Daniel,
Recently I passed the SAS Base Delta Certification and I achieved without going to any class or professional training. For the certification I Prepared using the material provided by SAS and SAS suggested books, I got those from Amazon. After reading and preparing for almost 3 months, I feel I should start some practice to see what actually I learn. While searching for the practice test papers, I found www.analyticsexam.com and after giving the free demo exam on the web, I feel this is perfect for me. I purchase the premium account and man, this web was so useful, the tests are designed very neatly and as per the SAS's format. The best part is the result history, which helps in planning your next move.
The success of SAS Base boost my confidant, I am planning for my next Certification soon.
