Really good lecturer, he makes an effort to make the content relevant and interesting. Labs were mandatory and worth 10% overall, lectures weren't. Midterm and final are mcqs and make up 75% of total grade, they weren't that hard but you definitely had to study to be getting 90%+. Overall interesting course and can do well without too much effort.

GREAT professor, he does iclicker for lecture, so attendance mandatory, 2 midterms and a final, but multiple choice and he allows a cheat sheet for all three tests. section was alright, but pretty boring and the labs were very tedious. alex is attentive and will always answer questions during lecture and cares about you knowing the material.

Great guy and down to Earth. You can tell he loves his job. Go to every lecture and read the book. Also attend every lab and do good on the quizzes because your grade will drop big time if you dont. Only thing that really annoys me is how important the midterm and final are if you dont do good on those you won't do well. Will curve grades.

Wrobel is a great professor. His lectures are straightforward and easy to understand. In Earth 4, there are random attendance checks, and you get extra credit based on how many lectures you attend. Earth 4 is relatively easy, the labs in each section are not difficult and you can ask for help. Great professor who cares about his students.

Loved this course! Genuinely the only lecture I was excited to attend every week. Super interesting content and really made me consider doing an earth science minor lol. Tests allow cheat sheets but do have some tricky questions here and there. Labs are also fun! I ended up falling behind but still managed to get a decent grade bc of cheat sheets.

Alex is an awesome professor and is very understanding. Cheat sheets are allowed for his midterms and finals, only assignments are in section and some weekly quizzes. Pretty easy class as long as you pay attention. 2 midterms so it does feel like not much time in between tests. Loved this class and would definitely take his other classes.
