Not too easy. Not too difficult.
The course isn't very difficult because Dr. Scala makes it interesting in his own way. He gives very helpful study guides right before the exams, and tells you what to focus on. There is one lab report you have to do, which does take effort but not impossible. As long as you review the lecture slides before or after the class you'll do fine. I never bought the textbook. The slides were good enough.
I learned how to use a microscope, prepare my own smears with bacteria in it, and be able to identify a bacteria by looking at its physical characteristics.

Advice for students:
Go to class, and ask questions. Also participate in class, you get graded on that portion as well.
