Not difficult, 2c discussion board posts a week. 4 exams throughout the semester. If you time it up right, can be a very light workload for you.

She is very organized and prompt. Can come off intimidating but will be helpful and accomodating for circumstances.

Read her discussion board posts, she guides the discussion and pulls from exams from them. Also, read the supplemental material she posts for the course on that module - she asks 10-15% of exam questions from the supplemental readings.
