Hi myself Pranjal and I was preparing for SAS Visual Business Analytics (A00-278) certification from last 4 months, but somehow unable to gather the courage to sit for the exam. Then I got to know about this practice tool, and I had given a try, and I feel I mad a right decision. Practicing here made me perfect and provided the courage and positive energy I needed. I have passed the exam with great marks and that is why I recommend practice here to all.
All the best.
