I have a degree in Chemical Engineering from Caltech, so I was confident that I would have enough background to be able to follow along with most of the science. I've never taken any classes (in college or online) in the area of planetary science, so this was my first exposure. I thought most of the lectures were fascinating, and I learned a lot about planets and other bodies in our solar system. The homework questions were challenging, but reasonable. I loved all the pictures from satellite and telescope images. I also discovered some websites through this course that I'll definitely revisit. This course also showed me how little I know about geology and how fascinating it is, so I will be looking for some geology MOOCs to take in my future. I definitely thought my time was well spent.
