Good side and bad side of school

Good side and bad side of school
Well in general, I would to say that about good side and bad side of school. There is always s bad side to something that has good side too. There are over a billion schools in the world. All of them good and bad side. In school pupils learn any subjects and knowledge and again they learn rules of procedure, manners and ethics. Respect for adults. These are good side, but pupil learn these are in starter grades
Actually , I think I need school into the 9^th grade. Because there all of subjects in school. However, I need inter to studying, there for I need prepare for studying during 9th and 11th grades. So I needn’t the others subjects. I must study my important subjects and for this I leave the school and I must prepare hard on my only main science. It is my opinion for schools.
