  • Dave is awesome. Practice quizzes/finals reflected well with actual quizzes/finals and as long as you understand the processes they aren't too difficult.

  • Very useful for future courses in the degree, especially ENVE 225 in 2B.

  • Practice quizzes are extremely similar to the actual quizzes, same for the final. The course moves a bit fast at the end but if you stay on top of the practice problems the final will be manageable.

  • I usually struggle with math courses but I still enjoy most of them. However DE was definitely not my thing.
