POLS 207 with P See Lim

Have any of y'all taken or know anyone who has taken POLS 207 with P See Lim? I'm a freshman and I have no idea what I'm supposed to be gathering from her lectures. I've read the chapters in the loose leaf text book but they don't follow her lectures at all. She mostly talks about random graphs so I'm not sure if I should be memorizing the random stuff about Utah or Mississippi or if I should be looking for stuff about Texas or what. I have no idea what to expect on the tests at all either. I know they're multiple choice but are they on graphs? If so, what graphs? I'm already stressing about passing this class because I feel so lost in it. Thanks in advance
