The tests are pretty tough and you have to really use your sense to get around the tricky options but I guess that makes sense with the online format. Dr. Grace is kind and accomodating for the most part but can be a little cold sometimes although I think that's necessary.

Try to keep up with the readings. I had a system where I would do the lecture once and make notes, read the book once, and then when revising for midterms I would read the book with the lecture notes to see where they overlap and what the most important parts of the chapter are.
