How to write parents' positive comments on the school? Just keep it simple.

I am very pleased that my children's English ability has improved rapidly during their study in this school. The teaching attitude of school teachers is rigorous and serious, and children often mention it. Moreover, the exercises are of high quality and moderate difficulty, which is very beneficial to children's learning. On behalf of my children, I thank the school. I believe the school will cultivate a considerable number of outstanding talents.
