Cooper's lectures were used so I am not too sure how Hyun-Jung actually teaches. The content was pretty difficult to me but the tests are similar to the practice test, so if you do that and the homework u will be fine. She accommodated to students wishes. Grade was from 3 midterms and a final + homework, so a lot of pressure to do well on tests.
Material was tough but the practice exams were literally the same as the final so if you redo the practice exams twice before your exam, you will be okay. However your lowest exam grade will not be dropped. Also prof seemed inconsiderate when student emailed them about being sick.
