в 3 лицо сделать текс про других At the age of 16, we write an examination called GCSE (General Certificate of Secondary Education). We usually study from 8 to 12 GCSE subjects during the Years 10 and 11; and then choose subjects we will have the exams in.
After Year 11, we have to decide what to do next. There are different opportunities. Some of my friends decide to go to colleges of further education, which prepare students for work, and I will go to the sixth form. Most secondary schools have sixth-form departments but there is no such department in my school. That’s why I will go to a special sixth-form college. I like it more because at college the atmosphere is different and pupils are treated as adults. At the 6th form stage, pupils are highly specialized in three or four subjects and take A level exams. Good A level results in at least 3 subjects are necessary to get a place at a university or Art and Music College to get higher education. But not all pupils will get higher education after the sixth form. If you fail A level exams, you can go to colleges of further education or start looking for a job. But I hope to get a place at a university.
