Awful

Doctor Vaughn is absolutely the most horrible professor I've ever had in my life. He's terribly awful when it comes to class lectures. Also, he will zone out and start tangents on an unrelated subject. I can say that the homework did not cover the lectures in class nor the textbook. He will expect you to be knowledgeable like him on this subject.

Average

Prof. Mark is the nicest prof you'll ever have! Thermo is really tough especially when you have lots of errors on your notes. Actually, he's so much better after covid because he had to prepare his lectures well. You'll pass as long as you try to learn on your own and ask him for help.
