The best web

I was preparing for my SAS Visual Business Analytics 7.5/8.3 certification. I have done one SAS certification before as well, but this time as I am working, I have less time to prepare and the exam level is also high. I asked for advice and I received the name of this web as a suggestion, I have started preparing here by paying 41$ and that was not a big amount when I compare the fees I paid for my earlier exam for a full-time class. I feel I would have saved 200$ if I have opted for this web for my earlier exam as well. This time I received higher marks compared to my last certification, this time I have cleared SAS A00-278 with 89%.
Thank you.
