My favorite professor this semester! Otto's lectures are super engaging, he's funny and clearly enjoys his field, which makes you as a student want to be there for class. He posts all the same slides from lecture online so if you miss class no worries, it's all there to review. 3 exams and a final, if you go to SI and STUDY, you'll be fine!

Dr. Otto is amazing! He is a chill prof and really funny! His lectures can get boring but he plays videos during lectures that can be really interesting. The grade is only based off 3 exams and a final; however, he gives review sessions in class so it is best to show up to lecture to better understand reviews.

The grade is only composed of 3 midterms and 1 final. During my semester and one midterm, there was an issue with not printing out enough midterm copies so he gave everyone a 100. However, the midterms can be very tricky and wordy. The midterm 3's class-average was a 66%. Very low for a 100-level course like this. The first midterm was fairly easy.

Finished all the work for this semester-long class in the first 7 weeks. 5 quizzes + 1 final exam. The final is worth ALL of the points, basically decides your grade, which is a little nerve-racking, but just take thorough notes from lectures+copy down the questions and answers from the first 5 quizzes and the whole class is SO easy and enjoyable.

You could finish the whole class in a weekend, I spaced it out (1 quiz a week, then the final) and finished in 7 weeks. Easy to do well if you take thorough typed notes from voicethread lectures. Definitely recommend for non-ecol majors!

Amazing professor and makes science super fun, even when it's not been my favorite subject.

He will also go over what will be on the exams and let you know during lectures specific info that will be on them. Don't leave class early!

Hans Otto is a solid professor who keeps things entertaining and informative during lecture. While attendance isn't mandatory, it's key to stay on top of the topics discussed to be prepped for the exams (the only things graded).

There is no study guide or really even hints as to what to study, essentially you need to memorize all 8 powerpoints that are 30-50+ slides per exam. Some material on the exams wasn't even covered in class. Additionally he told us to not worry about taxa names and then proceeded to have multiple questions with them... AVOID THIS CLASS AT ALL COSTS

Prof Otto's class is made of 4 exams and the final, and there is no homework or readings. That being said the class is heavily lecture based and the test rely on the information in his PowerPoints. The class in my opinion was fairly easy, if you took high school biology/ AP biology this is a very nice review class as an intro to many STEM majors!

This class was the worst class I've ever taken. The time when I enrolled in his class his rate was 4.9, so I took him but I regret taking him now. After the semester, he even sent emails to students that his rating was falling and he could have provided help to the students if we had contacted him. But, every time I did he just said it is the same.

He made an easy class difficult. I felt some test questions were unfair and not mentioned in lecture but could not bring those points up because he never handed back exams. He reused questions from exam 1 on every exam, and I still don't know if I got all of those questions right. He was a boring lecturer who basically read off slides.
