My brain is getting tired!!!!

So I don't think I have learned this much in such a short period of time since High School.....OK maybe not even then!! ;) There is a lot of information coming at us right now and all I can think is that my brain is tired! This week coming up I have 3 tests!! I can hardly imagine how I am going to get through all of them not to mention passing off PE's in clinic. I know I will but when I look at it all I get a bit overwhelmed!! One day at a time I think is best!!
