This test is horrible in it's questioning and delivery. none of the questions relate to the material in a manner that is conducive with what was demonstrated. One of the many examples, the course repeatedly states 'verbally' that the MC of wood before kiln drying could be 25-30%, however all of the 'written' material onscreen states 28-30%. Another example is, there is no way to know if an answer is multiple answer, for example, what do pin and non-pin meters do. Both of them can be used to compare readings across an installation, measure a substrate and a non-pin meter can even measure MC of concrete. Along the same line, there is only 1 question that says 'choose 2' answers, while some questions allow you to check all or any answers and others still can only have one answer selected. I challenge the accuracy of this test, not in the scoring domain, but rather in the argument of whether or not answers are being graded correctly based on the question, answer and corresponding information provided in your presentation. Lastly, the order of questions contradicts itself, as the two regarding expansion in boards state that they should be one after the other, but they appear in no such manner. This was a waste of time.

I had a lot of issues with the Power Point The Audio did not work at times and sometimes the background music over took the teachers voice and the videos were way to fast. i had a few slides that the photos would not load and the voice over would just keep looping non stop. With all that aside I did however learn loads and wanted to thank you for your time in putting this online class together and for providing this Service.
