I am impressed

The practice test for SAS Certified Data Intigration Developer was very important for me at the time when I was having very less time left to prepare and pass. I have started and in a few days, I got to know about this web, I have subscribed to and start using. After almost 5 days, I was so confident that I have preponed my exam schedule and given an exam a week ahead. Passed with 88% !! :)
