I thought the course and materials were well written and easy to follow. There was a great deal of fundamental teaching material that was new to me along with quite a bit I was already familiar with. I did feel that while the video content was well made the course would have greatly benefited from having more of it, as 95% of the course consists of reading segments. More video media to accompany the reading material would have been appreciated. I also felt some of the tests had too few questions to give an accurate evaluation of comprehension of the reading - there were times when a simple misunderstanding of a question would reflect disproportionately to the overall score of my understanding of a given test. Overall however I felt the course was well designed and helpful for the purposes of TEFL/TESOL instruction. I am currently waiting for my certificate to be sent to my address as well. It may be delayed due to the global COVID19 crisis but I hope for it to arrive soon.
