How to not get grounded when you fail a class

The first thing you gonna need is to have a car. A new would work better but a decent one can also work. When you have the car, go to your parents and tell them that you crashed the new car you got or they bought for you. The moment they hear the bad news, they gonna freak out. When they seem angry, then you tell them that is a joke and that you just fail a class. For this to work, you need to be fast but not so fast. Try to practice with friends and good luck!
