Simulated exam ambiance with 970+ questions

I did not know about the LSSA-BB premium simulated question bank on this site earlier but most of my friends were able to clear the LSSA Lean Six Sigma - Black Belt certification exam, i was pretty surprised. I asked one of them and he directed me to this site and i was very much amazed with the layout of the site and all the sample tests. I attempted the sample test then and there and voila! I cleared it too. But i read the disclaimer that the questions are basic and simple and the real deal is faced in the subscription of the premium membership. Taking it was my best decision ever.
