Final test was harder and more specific than expected. If the question has more than one answer, it really needs to say "Mark all that apply".

I learned so much in this class! Erika Zavaleta's video field trips and lectures taught me so much about the place I live in, and it's amazing that it can all be accessed for free!

Really interesting and easy to apply to your natural surroundings if you live in California. I really enjoyed the videos, and learned a ton!

Fascinating and thorough course. I learned a ton, and the videos are dense with information. However, the quiz and discussion questions often felt like lazy afterthoughts.
