I study at boarding school. It is a school for girls
aged 11-18. The best thing about boarding is that you are always with your friends. Besides, it is the best way to get a good education. The teachers encourage us to work our best because they want us to succeed in life. We are never afraid to take tests or exams. We can go and see a teacher for help anytime. We study all the compulsory subject and there are a lot of optional subjects. The discipline is rather strict at school. We watch less TV than we did it at home but there are a lot of other interesting activities to take part in. In the evenings we do anything from dancing to playing games. We go on school trips and do a lot of sports. But, of course, I sometimes miss my family.
