Two possible problems: 1. It seems that to review a section of the course results in having to go through the whole course again. I asked iHasco about this, and was surprised to find that a score and certificate was available before I thought had completed the course - hence the second possible problem. The support assistant seemed a little too rushed to assist. 2. I'm not sure the on line course I followed functions properly. I have asked iHasco to examine why my score and certificate were available before I had finished answering the questions at the end of the course.
