PHIL160 . Zylstra S J 9 Months Ago

The grade is basically made up of 3 essay like exams in which he has very high expectaions i did really well on them esspecially compared to some of my classmates and i recieved a pretty low grade with little to no explenation. It feels like he placed me in a b grade category and was out to give me a b regrdless of my effort a shame

It's pretty hard to get above an 89%. Be prepared for in class essay exams. He usually gives the questions before the test so there's ample time to study and write responses.

Zylstra is one of the best professors in the Phil department. He is super caring and wants his students to do well. 3 Papers and weekly reading questions. Clear grading criteria and easy to do well. Would definitely take again!

Class wasn't bad, you don't have to purchase a textbook, but you use iclicker and the subscription is like $17 for the whole semester and you use it for reading quizzes at the beginning of the class which is also used for attendance. Not much work besides the readings before class and the in-class activity. tests are pretty light.

Took this class as a GE (pass/no pass), be prepared for very uninteresting material. All the homework was pretty easy, and the tests didn't take too long to study for.

Pretty much the entire grade was based on two midterms and a final and the multiple choice was very hard. I normally do incredibly well on multiple choice but not in this class. This was the first class I got below an A- on. The class wasn't that bad but it was quite dissapointing.
