I honestly have no idea why his rating is so high. Gives you a template for lab reports which helps but on the same note the labs are graded so meticulously. Not very accessible outside class and definitely not empathetic towards students, sometimes insults passive aggressively.

Love this guy. Likes to joke around but knows his stuff and teaches it well. Don't mess up your lab reports, go to his office hours, and quadruple-check your calculations. Midterm was easy if you study and final is easy if you know everything CONCEPTUALLY. Don't memorize, understand. Good at getting you to learn, not memorize. Wonderwoman superfan.

We had 5 lab reports and two exams, all of which were ridiculously challenging and didn't reflect lectures/labs. You needed to state absolutely everything in the lab report despite the page/word limit. He seemed like he was genuinely excited when he talked about students failing his exams. Grades do not reflect effort or competency in lab.

I heard that Professor Leigh was a bad professor before I took this class, but I actually really enjoyed it. Professor Leigh wants his students to do well and provides a lot of important information in lecture, you probably just have to rewatch it to make sure you absorb/understand it all.

The class grading was based entirely off you remembering a tiny detail he included in a lecture 4 weeks ago. He never told you what you should put on your lab report and graded you based off including some minute ridiculous keywords in your lab report. Rubric was based around penalizing on as many things as possible. Horrible professor & uncaring.

Prof. Leigh is by far one of the best chemistry prof. I've had at UCSD. I'm not a chemistry enthusiast, but his explanations are very easy to understand. Exams are very conceptual based, so know the material very thoroughly. Discussion are mandatory, but fairly light. If I were to take Chemistry again, I would definitely take it with Prof. Leigh.
