Prediction to Breathing Underwater

I am half way through reading Breathing Underwater by Alex Flinn. So far a boy named Nick had a good life until he got in trouble for hitting his girlfriend. Now no one wants to be his friend. he is being forced to go to Anger Management classes and to write in a notebook. I left off reading when nick was about to get in a fight with Leo because Leo stood up for him and Nick didn't like that but Mario, the class teacher, told them to take it outside. I don't think Nick or Leo will do anything.Everything will just calm down they will go back to the class. This a great book to read.
