While I did not get an A in this class, the quality of Mellor's course was so excellent that I would take her classes again without regarding grading (and grades usually depend of the TA anyways). Her lectures are very rich and dense, while extremely informative and insightful. So I recommend not to miss any of her classes. Her lecture style is mainly verbal with maybe some Powerpoint, but I was never bored for a second in any of her lectures. Readings are not unreasonably long - doable. Exams are straight from lecture material, in which he covers readings (so of course, you need to read). Requirements: a couple essays and a final (and weekly discussion posts depending on your TA).
Mellor is a true scholar who can change the way you view literature if you let her. So if Early Romantics is a time period you are interested in especially, I would highly recommend her class.
