Well, this turned out to be helpful

Yes, it did. It was not the first time that I have cleared a certification exam. Earlier too I had attempted one and cleared it successfully. I am thankful to the premium simulated question bank with detailed result history feature online. So just like last year, I chose the mocks to clear the Alibaba ACA Big Data certification exam. The reason being I did not want to try anything else and waste my attempt. I always repeat my success by doing the same things that I had done earlier. This is not superstition at all, it is way of my life.
