His class is very fast-paced, and you need to keep up. Often the only teaching he does is off of a slide show, and you're on your own from there. Strongly recommend review what you learned daily, instead of cramming all the information the night before a quiz or test. He is helpful when you are confused about a subject, but it isn't always as clear. Also strongly recommend watching YouTube videos such as Amoeba Sisters, which has tons of helpful videos, to help understand concepts even better. This class requires a lot of memorization, using flashcards or Quizlets will be very beneficial.

For biology, definitely do the work!! He'll present slideshows almost everyday and I encourage you to take notes that YOU can understand, don't just copy them. I also recommend that you do something every night, his tests are based off the labs, and notes and so frequent review of the material is key to succeeding in the class.
