I must admit using the CE Shop gave me free time to complete the courses. A one-hour course does not take one hour; a two-hour course, does not take two hours, but even though it took longer to complete, I learned more and felt very confident when taking the tests. The information that we should know, is not always apparent, this is a very good learning tool and inspiration to take these courses in the future as a refresher. The downside of taking the courses is the many cases/examples to be read before completing the course. A few good case studies and a few good examples might go farther toward retention than many that become redundant.
