Is an interesting, amusing guy who does his best to make class interesting. He is genuine and cares about his students and their success. His tests are large and besides a few grade-building group quizes, in class, they're the only grades. He also has anecdotes and interesting examples to simplify things, and offers a break in the middle of class.

Dr. Allred is seriously among the best university professors I have ever had. He is hilarious so it makes class enjoyable. I liked how he played music before class. His teaching is effective, and he is really knowledgable about biology, but you have to go to class because the exams are based primarily one the lectures, not the book. Recommended
