SAS Big data

Hi Guys,
I have a print of my results, which says, I have passed the certification SAS Big Data Preparation, Statistics, and Visual Explorations :)
I have used the practice exam service from for almost 20 days, not daily infect, but this has helped me pass the exam in the very first attempt. In the beginning, I use to get confused with multiple answers even though I know correct answers, due to confusion, I use to get it wrong. Slowly, I understand the logic and become more confident. I just love this technique for preparation and recommend to all. 
A big thanks and thumbs up to you guys.. :)
