Armando is so sweet, he is really passionate about what he does. He did a great job with zoom lectures. Tests were quite difficult if you didn't know your stuff. The labs were fun but took some time. Textbook was very useful. No attendance was taken for attending lectures but you really should attend if you want to do well. He goes through many examples and explains concepts clearly.

Read the textbook and do lots of practice problems, it will be worth your time. You have to work at it all the time to understand what's going on.
