If you need help use Dr. Patrick.
Dr. Patrick and I went over both cellular respiration and fermentation. I think the thing that helped me the most was that Dr. Patrick had his own lecture slides and could reteach me the whole thing with material that he understood. He also did a fantastic job of breaking down complex topics into simple to understand ideas. If you are a college student who needs help with biology, like I was and still am, I highly recommend using him. I will most definitely use him again
