this presenter was very knowledgeable and knew the material. Terms used were sometimes confusing and a little too technical.

There is possibly one typo in an answer choice. One poorly worded question that appeared to be a Check All type question but was not.

Excellent course. Very clear explanation and examples to go with it.

Very good explanation of Inverter operation and reference to code compliance and overall maintenance benefits. I felt that the quiz did not follow the presentation and use of some acronyms. And then, I may have missed those explanations.

very informative

Excellent presentation. The graphics really helped in understanding the basic concepts. The type and delivery speed of the information was good for architects that have no strong knowledge on this subject.

Good diagrams helped illustrate the topics. Thank you.

bit more modulation to voice

I think this was one of the best lecturers I've ever heard.

One of the better online courses. Simplified diagrams and measured pace are both helpful and appreciated.

It was packed with information I normally don't com across and found it informative but a bit over my head as an architect.

Your three courses were very good. ISO-1002 is more valuable to electrical engineers than architects. As an architect I did not fully understand some of the terminology. This point is no reflection on you, just my limited electrical knowledge. Courses ISO- 501 and 502 were very useful.
