Hii @sohana1 I hope that you are doing well.Thanks for sharing your quality blog.Principal of the school has so many responsibilities to manage such as maintain discipline ,manage the staff etc.

I will arrange extra classes for students who can't adopt lessons quickly or fast

This will be the good practice that will help the weak students to learn more to cover the syllabus.

Sports helps the students to built their personality and boost their physical and mental health as well.By the active participation of the students their confidance increases which also enhance their learning capacity.

You have written well.Good luck for the contest.
