excellent
Great course overall. Detailed coverage of the subject. Learnt a great deal of information. There is alot of content to cover and hence not much time is spent reinforcing concepts. Also, marks arent recorded in the free version of the course to allow you to track how youre progressing. Waiting to see if notification appears in completions. So far i havent seen a notification of course completion under completions or achievements. This may take some time to appear though.
Excellent course overall. I learned a lot and it sparked my interest to study more about astronomy. The only caveats I have to offer here are that this course is not for total beginners: a student really needs to have a background in basic calculus and physics in order to get anything out of the course. Sometimes it feels like the professor is presenting results at a research conference rather than teaching students with no astronomy background---which can be exciting to watch but it can also be baffling to beginners. Also, I felt the course presented a little too much material for a single session, perhaps the course should be split into two parts? Other than that, highly recommended.
