You have written well about the topic,a principal is the person that have the responsibilities of the whole institute.

I ask teachers to focus on rules.

Rules are the significant part to maintain the discipline.The students that follow the rules must be awarded this will encourge other students to follow the discipline.

Sports and other curricular activities tends to boost the learning capacity of the students and their mental health also remains good.

Thanks for sharing your quality content.Good luck for the contest.
