One of the worst professors I have taken here, does not care about the students and clearly was just ready to retire. No compassion for students, tests not representative of what is taught in class, basically have to teach yourself as you study the hundreds of assigned problems in the textbook. At least he's not teaching anymore

The class is challenging, but Christoffersen wants you to succeed. His lectures can be scattered, so be sure to use the textbook and practice problems. Unstuck AI was a big help for me on exam prep.

Honestly a nice enough professor with reasonable expectations and class policies. Not great, but not even near the worst class/professor I've had here. Pay attention, do the practice problems and it's pretty much a guaranteed B.

Great professor, I really enjoyed this class, It was super easy homework-wise and also very interesting. He's a great guy and you can tell he enjoys teaching the subject. Take this class!

I respect his expertise in genetics, but I feel like he does not know how to teach this knowledge to students and/or make lectures exciting. Many of my peers who attend lectures also agree his many of his problem explanations are confusing. However, I appreciate the additional practice problems he provided and his occasional quiz hints.

He is nice enough and wants people to succeed, and I thought his tests were reasonable for the most part. They are very similar to the practice. His lectures are a bit all over the place, I feel like he would mention something once and it would show up on an exam. He made the class total the average of the top 10 scores. A bit condescending though.
