Pretty easy class. only 1 mid term and final, and final was not cumulative. If you studied his study guide, then the test is a breeze cause most was multiple choice with some free response. Homework was pretty easy too if you pay attention to the lecture or you could just search up the answers. Discussion is graded on participation. Even though the class is very boring, Prall is a pretty good lecturer. Be prepared to memorize a bunch of random primate names. The memorization gets really tedious. I didn't want to memorize the names to heart, which is why I struggled a little bit on the final.
