I'm thinking of locking him in a closet after viewing his report card.
Are you expecting bad grades?
Yes, I think it is going to be a terrible failure.
You shouldn't punish your son for failing a class. It is a good lesson to have in life. It will teach him how to get back up.
My shitty son always fails, I'm ready to give up on him. I just want to beat the shit out of him.
You can't punish him physically. Have you tried asking him what is going on or if he needs help? Abuse is not a solution it will only keep him in failure when he might need a tutor.
