I find it very clearly presented and well organized. I really enjoyed it. Thank you! I liked it so much that I decided to translate it in my mother language so I can refresh the notions learned.

Great Beginner Course. There are some parts where there will be frustration, but the forums are helpful. Any type of class involving math and science involves practice and work. Professor is great!
