Attendance Policies

I am kind of upset about the attendance policies because I might not be able to go to championships for tennis because of them. It is ridicilous that blue cards don't matter to some classes, and also that you only get a certain amount. No matter how hard you work for a class, the attendance policy or parcipation policy always seems to get you somehow. I really hope my professor understands that this is important, and that I also will be at every class after this. It's hard to do when the teacher is not even coming to some classes. For example, my teacher is not coming to class tomorrow, so I want him not to come next friday! That'd be great, and it would make my life a lot easier! We are just giving speeches anyways, so maybe ill get off the hook. Wish me luck!
