Material is presented in irrational order, testing was about knowledge of solar panels rather than creative thinking. Marked down for an answer seen as incorrect - but checked against earlier material was correct.

Garbled course with repeated material.

Excellent course!! I have learned a great deal, strongly suggest everyone to take this class. Suitable for any age though I think this should be taught as a required course in elementary school or younger age.

Thank you to Professor Childs for making the course available. Great course material.

I've found the tools provided by the course really useful and inspiring. Thank you
