about advertisements in schools

These days, some school do not have nough money to pay for all the programs that they think are necessary for their students. as a result, some school are considering allowing advertisements in their building. I think it can be a good idea. Actually, my school is like the school that has the nicest located. So the principal doesn't want his school to have a bad image so they do not allowed advertisements but actually all of the schools in my country don't allowed it. One more reason, that they scared some people will have bad advertisements like "Welcome to ciagrettes club", some things like that. And other things, if some schools do not have enough money to pay for all the programs they will still teaching like before. If you don't want to then you have to do a test to go to a good school that had all the programs and the homework there will be harder and more than other schools. I hope you know more about schools in my country. Thank you for listening.
