Music in Society

Music in Society isn't at all what I expected and I'm struggling big time, seeing it on my schedule  I thought it was learning about the different types of cultures and music in society but that's not at all what it is. It's an actual music class and I have no idea why I am forced to take this class. Last time I have taken a music class was back in like 5th grade, ever since then I had no classes related to music until now. In this class you have to know the notes, pitches, rhythm, how many people are singing, and other things I have never heard of before and this class is hitting me fast. Trying to study is hard too because last time I studied for my first exam in this class half of the stuff on the exam wasn't even on the exam review and I have no idea what to study this time and this upcoming exam is going to be ugly.
