I have had experience with the ASQ Exam Bank, the QCI primer, and QCI CD for CQE exam preparation. (I teach CQE Exam preparation courses.)
The QCI material is good and has the advantage of a feedback loop on questions and answers over the past twenty plus years.
The ASQ exam question bank is very new, does not have as good of explanations to some of the questions but the questions are modern (unlike some of the QCI questions).
I have used the term modern to mean "does not conform to the ASQ Item-Writing Manual" criteria for a question.
For instance the following question which appeared on the 1972 CQE exam and appears in the QCI Primer and QCI CD would not be allowed on the current exam or in the ASQ exam bank because it tests three main ideas and the criteria states that it can only test one main idea. It is therefore too complicated for the current exam.
"Two components A and B are working in series as a system. Component A has an exponential failure rate of 3 x 10E-04 failures per hour. Component B is normally distributed with a mean of 600 and a standard deviation of 200 hours. Assuming independence, calculate the reliability of the system after 200 hours. (Answer 0.92)"
