BIOCHEM 501
Quality 5/5Difficulty 2/5
I thought he did a really nice job with his section. He is very responsive, and I thought his lectures showed he wanted to help us succeed. Overall, very matter-of-fact and good at instructing a tough unit.

Let me retake an exam I had missed, very understanding guy. Do all the practice exams for this class they will make it a lot easier

BIOCHEM 501
Quality 3/5Difficulty 3/5
Pennella is a good professor for the tougher unit in Biochem 501. He attempts to make the course more easy to follow but it's really up to you if you're into Anabolism. The class is exam heavy with 4 exams but each exam is noncumulative and easy if you put in the time to study with the practice exams and drawing out the complex pathways.

Quality 5/5Difficulty 3/5
Despite some of the other ratings I found him to be the easiest to understand and follow along of all three lecturers. He is also extremely accommodating with no complaints, which I really appreciate.

Very kind and cares about students. Very difficult material but, so he makes the effort to hand write some of the material and organize it in a way that helps students.

Dr. Pennella's lectures were always very interesting. Outside of class he was also very friendly and showed he cared about the students.
