About this rating

Raw average: 1.78/5 from 73 quality ratings. The adjusted rating blends this with the UW review average (3.66/5), weighted as 20 additional ratings. Smaller samples stay closer to that average. Each captured review is counted once in the prior; this does not correct who chooses to leave a review.

Thinking about this class semesters after taking it. If you're signed up for the fall, I am warning you, drop! It's boring, unclear, and exhausting. Please drop. You will be frustrated more than you can imagine.

Honestly wasn't as bad as these ratings make her seem. Lectures were very structured and helpful in my opinion. Practice exams were given and made studying extremely easier. She also provided many extra credit opportunities just for showing up to lecture.

Incredibly difficult to follow understand her lectures. I came out of this class learning nothing.

It is frustrating that we don't get reasoning behind quiz and exam scores. I emailed her about this and she didn't seem to care. I sometimes feel she just throws a scores at a dart board. Aside from unclear grading criteria, the class is hard to follow and it is pretty miserable. Final was long and unexpected.

the professor is gentle and her ppt is structured. Hw is not important but the topic of quiz is kind of random. I think the most tough thing for this class is her final, which is not related to the past exam and is really difficult (midterm is easy and is similar to past exam:)
