Pass the certification exam with 90% was a great great help for me to clear my SAS ADVANCED CERTIFICATION exam... 
I have already attended coaching classes in Hyderabad  and attended first unsuccessful attempt  in May month first week.
Then one of my friend has recommended this practice exam which helped me understand the exam pattern first of all as repeating practice exam  attempt helped me set an answering pattern which helped giving all the answers well with in time. Also helped me understand the way they twist the questions.
Big thanks to the team working for keep the data updated and help the student at very nominal price compare to the classes fees and other dump selling sites.
I recommend this practice exam to all SAS students.
