School authorities itself should come up a plan on this. (They are the best to solve this)

In my opinion the kid should bring the books back Home. As the parents should observe, whats going on.

A teacher can not be a parent. If He Or She is, Then she/He is a real teacher.

How ever, Let me suggest my opinion, that is, reduce number of subjects for a day.

Example, let the kid study 4 subjects for a day instead 8.

This is a humble opinion of mine and I am requesting the other parents who has creative ideas to post on to this forum.
