people are crazy

So, I have this peds class. There's quite a bit of information that we need to know for the final, in Dec. I'm not really that concerned with it---it is 3 months away. But, everyone in my class is freaked out about it. There are currently 10 emails in my inbox on how to study and that we should form a giant study group to go over the information. With each of us making notes and copying them so that we all have each other's notes. Granted the professor is a bit disorganized, but the stuff she goes over she covers well and she has stated numerous times, that if it is presented in class it's important. Are these people overly crazy or am I too relaxed?
