I am fully satisfied with Initially. When I have started I have failed by just 2 % short of passing score, even after studying at length. However the result with all the details of questions I got true or false helped me identify the issues and fixed it. I have started receiving 90+ percentage and even scored up to 98%. I can say that I have mastered this practice exam before my certification.
Due to this confidence, I was able to score 89% in my real SAS Clinical Trials Programmer Certification exam. I truly recommend to other candidates.
