How to skip one class without leaving school for the day
A class or two before the one you want to skip, start telling your friends that you feel a little sick.
During the class before the one you want to skip, for the first half act sick, but not too sick or the teacher may send you to the nurse.
Hold your stomach or prop your head in your hands.
About 2 minutes into the class, ask the teacher if you can go to the bathroom. Say that your stomach really hurts, you have a bad headache, or that you just feel bad all over.
