If self-control is poor, it is recommended to choose a full-time nursing class. If you have strong self-control, it is recommended to choose a school.
It depends on your old school. If full-time nursing can bring a good environment, it is still possible. Now senior three, my friend's school is a mess. She just chose a small class for full-time nursing outside. She said it's better than at school. There are few people but she is very serious. At least she studies every day. I think your son should actually have his own ideas. If he really wants to work hard, he knows what is better for him.
Whether it is good to repeat the college entrance examination in full-time depends on personal circumstances. If you are independent, after all, you are an adult and can manage yourself well. Under the supervision of teachers, it is good to have a full-time nursery class. If a person is very dependent on his family and his heart has not fully grown up, it is better not to take care of it completely, otherwise it will be very uncomfortable.
