Review for's practice exam for SAS Advanced Programming

What I liked,
1. Questions are updated and most of them are from real exam
2. Result history, this helped a lot
3. Good interface, even in the mobile or tab.
4. Competitive price when compare to other service providers, who have less feature still charging almost same or more
5. No adds and no-nonsense on the web.
What can be improve
1. Voice support can be a great feature.
2. Explanation to each question (even at little higher the price from current)
To summarize, I am very happy with the existing stuff for SAS A00-232 practice exam at USD 41,
Thank you.
