<p>I'll be taking chem 140A in the fall, and so far the profs who'll be teaching are O'Connor, Yang, Ternansky, and Perrin. I've heard that Ternansky is pretty difficult, and that O'Connor only has one midterm and one final. So I guess I'm currently deciding between Yang and Perrin. If anyone had any input, it'd be much appreciated!</p>
<p>I’ve only heard things about Perrin b/w him and Yang, so I’d go with him. He gives cheat sheets for exams! I took 140A with Ternansky and definitely DO NOT recommend him at all, unless you’re extra willing to put in the time and effort for his class.</p>
<p>I’ve never taken chem140a with any of these prof. Right now I am taking it with Albizati, spring quarter.
I’ve heard about O’Connor that he’s good as well.
