Good

Professor O'Neill is literally the nicest teacher ever. He's always willing to help. He will put biology into layman's term, which make it easier to comprehend. His quizzes were pretty easy, I got an easy 10 points. However, like every one is saying, his exams were tough. He is by far the most helpful and caring professor that I've had her at University of Wisconsin.

Average

Professor O'Neill is an extremely tough grader. My advice for this class is to read the textbook as it often gave me a better understanding of the subject material and gave a better explanation than the lectures sometimes. Also, go to his office hours. The grading system is simply A, B, C, etc., no extra credit or +/-.
