Great Source for preparation

I have used this practice test for 15 days before appearing for the final exam and found the same very useful. Question quality is great. In the Beginning, I doubt of wrong and erroneous questions however after doing a little research I found that the question is created in a manner where it confuses you on the correct answer and these are the type of questions what one faces in the real exam. After using it for 15 continues day, daily 2 to 3 hours, every time I got any wrong answers, I go back to my textbook and the web to check and this is how I improved a lot. I have not just mugged up the questions and answers but actually, understand the concepts. 
Big thanks to the team Analyticsexam.com, I pass My SAS A00-272 with good marks.
