Good deal at the cost as got accurate questions

Hi, Myself George, and I have used the paid service on this wen, that is their practice exam for SAS Predictive Modeler.
I know they can improve as some say in the earlier review by providing data sets along with the practice test, however, I feel at this cost, even if they are providing test contains the best possible questions which can help you pass would be a great deal. At least for me.
