Pretty easy, overall.
I loved the way Professor Foust lectured. She made them super interesting by providing extra fun facts about the material. In addition, she never had exams only quizzes.
Professor Foust has one quiz a week, and she allows you to retake the quizzes as many times as you need to for a 100. They are all multiple choice questions and it's very easy to narrow down the correct answer.
Hours per week:
Advice for students:
Be a good note taker. She provides powerpoint slides, but the bulk of what you need to know she states verbally.
