SAS Advanced Programming Professional Delta

Clear my SAS Advanced Programming Professional Delta certification today and got 91% marks.. 
I feel this web based practice tool is just wonderful.
I feel this has great merit over any other preparation methods as this helped me in identifying and fixing may issue with my understanding.
When it comes to questions, I must say the most of the questions were from this list, however i was so prepared that even if the questions went out of this list, I would have managed.
