Very engaging lectures and a great teacher. Has helpful reviews before the tests and lots of office hours for extra help. Cares about students learning and provides many resources. I don’t like chemistry much but found this to be one of my favorite classes.

Deifel is one of the best teachers I’ve had. It is clear that he genuinely cares about each and every one of his students. He makes himself available for all his students to address any questions or concerns. Deifel is funny, engaging, and made me excited for the 8am wake up (I know it’s crazy). He is incredible 10/10 experience.

Deifel is a very helpful guy, holds lot of office hours and is always open to questions from text. Lectures are engaging and Deifel is overall a very nice and helpful professor for what is a class that has difficult material.

He's a very fun professor, he has so many office hours and is free whenever to help students. He's very passionate not just about the subject but also about his students and gets to know almost every one on a more personal level!

Dr. Deifel is a godsend. I cannot express how useful his lectures are, the clarity of his lessons makes chemistry easier to understand. The nature of this class makes it challenging in itself, however, Deifel will hold you by the hand throughout the quarter and answer questions if you show up to office hours. Homework and participation are worth essentially 50% of your grade. Plus, the exams are relatively difficult but straightforward, so you will get a good score if you study. Definitely take this class if you can.

The lectures are important, but it takes personal devotion to truly know the material.

You don’t have to read the textbook to get an A, but you will need to spend some independent time learning in some form (Organic Chemistry Tutor FTW)

Deifel is really funny, and he really keeps the class engaged. Although it is my hardest class this quarter, I always look forward to coming to class.

His review sessions before tests are a godsend. If he didn’t do those, succeeding before tests would be a lot harder for me. The tests are hard, but he puts his best effort into being a highly valuable resource to you. Thank you Deifel!
