Writing: Should th government introduce school on Saturday mornings?

The government plans to introduced a new law which will mean that from now, on Saturday morning there will be school. It is a very polemic debate and perhaps we have not ever raised: would it be done according to the class on Saturday morning? In my view, this would have some negative consequences.
In the first place, I believe that it's too much school, I think this is not good for students because we have a while to play, socialize with friends and also to study, I think two days off is OK. Saturday morning is excessive. Moreover, this not only poses a problem for students but also not helpful, I think in life you can do many other things, like practicing a sport.
If the aim of the government is makin this law on Saturday I think it is crazy. In conclusion, I think it is a wrong law.
