My experiance with this practice exam site

Let me start with a confession that this was my 3rd attempt. Yes, I had two failed attempt before this. After failing for the second time, I dropped the idea of getting SAS Advanced Programmer certificate but one of my friend who had practiced on this site told me to give a try to this site. I started practicing on this 25 days before my exam date. The comprehensive result with all correct ans after each test helped me a lot in identifying weak areas and each practice test makes me more confident. I passed 
Thank you,
