I can’t review my scored exam upon completion. How come?


Unfortunately, we no longer allow students to review their completed exams/assignments. This helps to ensure the integrity of our courses.

It is important to keep in mind that many answers are “weighted”. In some situations there may be multiple correct answers, it is important to choose the “best” answer to receive the maximum amount of points.

Originally developed by Bill Smith at Motorola in 1986, the Six Sigma Training program was created using some of the most innovative quality improvement methods from the preceding six decades. The term "Six Sigma" is derived from a field of statistics known as process capability. The term 6 Sigma refers to the ability of manufacturing processes to produce a very high proportion of output within specification. Processes that operate with "six sigma quality" over the short term are assumed to produce long-term defect levels below 3.4 defects per million opportunities. Six Sigma's goal is to improve overall processes to that level of quality or better.
