Literally 20% of our grade came from something that was never even mentioned on the syllabus or spoken about in class. that was super shady

Terrible professor. Worst professor I have had throughout my undergraduate experience. She is very unclear, mumbles, and unorganized. Mostly, she is very unapproachable and is rude when students ask questions/clarity. Her response is "I am not going to answer that, I will let you think about it". This is a tough class and clarity is needed. Avoid.
