I am writing to put your mind on the poor English spoken by the students of the school. The students of our school are quite poor in English and they feel shy when they speak infront of a large crowd.
I am writing this to inform gou you that if won't took any important decision in this case the reputation of the school will be damaged, you can organize summer camp, extra classes or some type of quiz to encourage students to improve their vocabulary and english.
I shall be thankful if you would look in this case
