Useful for every beginners starting to follow their dream of astrophysics
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 for beginners. just one issue: the audio is very soft and is often hard to hear even in full volume. it would be appreciated if the audio could be increased a bit
