Two Thumbs Up from myside!

I signed up for the SAS Base programming Certification premium exams in order to prepare for the test. I took two practice tests and failed them; I passed the third practice test, I went a head and taken  two more attempts and passed those as well.
I just took the actual test two days ago and passed with good score. I'm certain that I would have scored even higher if I'd had more than one week to study and taken more practice tests. Actually, several of the questions were very similar to those on the practice tests, which was a huge help.
I can confidently recommend the premium exams for anyone else preparing for their certification. The only caveat is that there is no explanation of incorrect answers, just which option was correct. I had to google the questions I got wrong to get full explanations on other websites, however, at this nominal cost, this is more then enough.
Good luck!
