I hope you enjoyed the class. I'm glad that we had the opportunity, and have enjoyed reading your work. I must confess that I would have strongly preferred a face-to-face class.
Here's a final chance to get some blogging in:
What did you think of the course material?
What topic did you find the most interesting? Why?
What topic was the least interesting? Why?
Any topics that were confusing?
Were there topics that you would have liked to have seen covered but we didn't get to?
(My first pick here would be renewable energy, which I usually spend at least a couple of weeks on!)
Take good care and enjoy the rest of your summer!
