You have done a very good assisment of the topic. Ofcourse their is no doubt good study plan must take into account specially in childhood period/time. This is very much crusel time in person's life. The child's education must be first piarority but must also address their physical development too. It too much perfect, along with study and and learning their should be refreshment time for the kids too, to have good nourishment of their minds.

Good luck in the contest.
