I dislike Gails teaching style but plenty of people seem to enjoy it. Anything is examinable including videos that you watched for discussion posts which is annoying. If you have to take the course unfortunately Gail is the only prof that teaches it.

Online-oriented. Gail is Gail. The exams are a bit harder than expected, so know your facts!

Watch all the videos & take notes, make notes for all the supplemental readings/guest lectures, and take notes during her lecture (she tests on things she says, not necessarily on the slides).
