difficult teaching style he asks difficult questions and won't continue lecturing until they are answered. he was late to class almost every day. there were only a few assignments and there were multiple instances of confusion about due dates including the final paper. never posted any grades throughout the quarter and never handed back final exams

Doesn't stick to syllabus, consistently late to class, passive-aggressive to students asking questions, often smirks and ridicules students who answer a question incorrectly in lecture, does not continue with the lecture until his questions are answered by students, will not have completed grading any course material after week 6 until finals week.

Professor Clark routinely shows up late to lectures, is extremely passive aggressive when answering questions, and his tests require memorization of specific values & complex graphs. He does not follow his syllabus whatsoever; he completely changed an assignment the last week of the quarter. He is without a doubt one of the worst teachers at UCSB.

This class was very interesting if you paid attention to general chemistry and you find atmospheric toxins concerning. There is a moderate amount of studying involved; i.e. his lecture slides. If you attended lecture, paid attention to processes such as ozone production and acid rain, then his class was a breeze. Otherwise, you might be miserable.

By far the worst professor I have ever had. He has no interest in teaching. Quizzes and midterms have material never covered in the class because he says it is something you should just know. Incredibly boring and awful experience.

He's super monotone; long pauses between thoughts. Asks very simple questions, and won't move on till someone answers. This gets really annoying. Office hours are at weird times, and I feel he avoids talking to students. Zoom university made his class doable. Random pop quizzes are 20% of your grade, and impossible. Only material kept me interested
