SAS Base Programming certificate is the first SAS certification I achieved, but this was the easiest at this time I have used this mock test to prepare for. 
They have done a wonderful job, I must say.
The content is absolutely in sync with the course outline by SAS and the marking system as well.
Result at the end of the exam help evaluate and see where I did the mistake, this was most helpful as I know where should I improve. 
I am happy with the quality and stuff provided by www.analyticsexam.com in just $41.
I recommend this test to all who are trying for SAS certificate.
