I give a 4-star rating because it gives a general overview of the topic, giving room to build up a more comprehensive presentation.
good effort and work thanks a lot prof john mclachlan we need to see some video or links

The reason I gave this course a rating of 2 - is because the concepts are not explained very well, and as a result they are not conducive to understanding this science.
