I very much liked the idea of a single payment for two months unlimited access. The CSSYB mock exams have a system which is very simple and easy for already burdened professionals. I remained so relaxed during the practice of Six Sigma Yellow Belt certification exam. I did not have to go back and forth every time i decided to attempt questions.
2 months unlimited access! Yippee!!
