Reviews of professor Sierra Petersen

Rating: 3.0/5, difficulty: 4.0/5
She goes through her lectures quickly and gives weekly quizzes but all of the answers are in the powerpoints (which she posts on canvas). Very sweet but requires a lot of work for an introductory class. Thought this was going to be an easy NS credit but I wound up having to study a fair amount. Very nice person but not the class I was looking for.

Professor Petersen is a good person and cares about her teaching style. However, the way she tests her students is HORRIBLE. Her exams are probably some of the worst formatted tests I've ever had to take. For an introductory course, this class is horrible, especially if you are taking this for a QR2 Math Credit. Take an Astro Course instead.

Her tests are worth 45% of the grade but offers no extra credit. Her advice? Earn every non-exam point as possible. She talks very quickly through lecture and expects us all to just "get it'". VERY clicker heavy, but at least it bumps up your grade a tiny, minuscule amount. She should just be allowed to research. She is not equipped to teach.

Avoid at all costs. Ask anyone who has taken this course or heard about it, they will say nothing nice. HW is not related to lectures. Labs are not related to what you are taught. Three people broke down during lab crying and teachers wouldn't help them. Extremely hard for an introductory and not worth the extra time/stress.

Actually the worst professor I've ever had at University of Michigan. She goes extremely fast and doesn't do a good job of explaining concepts and then tests you right away. There's weekly quizzes that ask way more in depth than anything we learned in class and there's no textbook. If you're not an oceanography expert do not take this class.

Her lectures are lengthy and 70% of material is irrelevant. So many unnecessary assignments that don't teach anything, and tests are graded tough. Boring and not at all engaging, I would not recommend taking a class from her and can say 100% do NOT take Earth 222.
