The International Space School V.N. Chelomey was established in 1990 in Baikonur. Students at the school must study the same subjects as everyone else, but they have additional classes in maths, physics, biology, and chemistry. You must be between 11 and 18 to attend the school, and you must pass an exam. However, if you have won an Olympiad or an international competition, you don't have to sit for an exam. The rules are strict. You mustn't be late for class. The lessons start at 8.30 a.m., and you must be in the classroom at least ten minutes before that. Students don't have to wear uniforms, but they mustn't have to study very hard. They don't have to go to school six days a week, including Saturdays. There are a lot of interesting extra-curricular activities and clubs, like the rocket modeling club. You can choose as many as you want, but you mustn't sign up for more than two because you won't have time to prepare.
