Good

Professor O'Leary is a great teacher. He knows everything about earth science and has a punny humor. So, his lectures aren't too bad. But I wouldn't have taken the class if I had known that the three exams make up your entire grade and are all multiple choice a to e. The questions are very specific and answer choices are too similar. It's just that, the exams are just too hard.

Awesome

From Professor O'Leary's cable knit sweaters to his dry humor, he's a truly brilliant. Although his class is lecture heavy, with three exams to make up your entire grade, he will do a big curves and cares very much on his students. I will protect him at all costs. Overall, this course is worth taking for.

Awesome

Professor O'Leary was amazing. His lectures are only 75 minutes, with a 5-minute break in each class. His lectures were boring though. However, if you show up just to take notes and study, then you'll be fine. He drops the lowest exam as well. I attended his class every time mostly on my phone. So I got a 74 on the exams. Luckily, he did give curves so I got a B. Overall, he's a kind older man, it's only the exams that were hard.

Average

Generally, he's kind. But his classes were sometimes tough to understand and I didn't get a lot out of them. He's pretty good at explaining things when you talk to him individually. So, he can be useful if you have the extra time. There's a book for the class that you don't really need to get. But, who knows, it might help.
