EARTH115 . Rioux M E 7 Months Ago

The goat. Crazy work load, but the TA's and Matt himself are always willing to help break any questions down for you. Out of all the ES professors, I've learned the most from him! Super approachable, is passionate about what he teaches and wants you to succeed.

He knows his stuff, but I don't see myself taking another course by him again. He wasn't very understanding of family emergencies.

Matt is amazing and anyone at UCSB is lucky to be in one of his classes, genuinely such an understanding and kind person. Material in his class is difficult put he does his best to make everything digestible/accessible. 10/10

Lectures are boring, but if you pay attention and take notes you'll be good. Tests are extremely straight-forward. Labs are long and some are hard, ask your TA for help or guidance and you'll be fine. Labs make up most the grade, so engage with ur TA. Weekly quizzes w/ 5 Qs. 1 in person MC Midterm. 1 in person MC Final. 8 Labs. Iclicker each lect.

He puts whatever is on his slides on the tests. If you just go to lectures and write the notes about the lectures you will pass. Labs are pretty difficult but TAs are there to help. Nothing he didn't talk about in class will be on the midterm/final. Overall a super great teacher and will explain in detail anything you missed if you have questions

Great at office hours, kind person, flexible and responsive via email. Great lecturer and well-structured slides. Fair grader and moderately difficult exams. However, easily the most course work I have ever had for a class. He's the heavy weight of the department for sure.
