Перевод текста A) If you are a Year 11 student, no matter whether a boy or a girl, thinking about what direction to take after school, or a Year 9 or 10 student considering your future goals, you will be making important decisions that will affect the rest of your life. We offer a great range of courses for Post Leaving Certificate and for about students. Students who successfully complete their studies at the College get the necessary qualifications to enter their chosen career or to continue their studies at the third level. The education is free, however, there are sums of money that students have to pay to attend all courses: for example, registration fees, examination fees. Students will be informed at interview about the specific prices of their chosen course. B) The School is set on the edge of an attractive market town almost in the centre of England. School House, the boarding residence, is set in an attractive Georgian house. The House is comfortably furnished and offers an attractive «family» atmosphere to boys aged between 11 and 19 years. Entry into School House is by interview, not examination, and the important criteria for selection are a willingness to live happily and study effectively in a society of boys. We have very competitive prices and, with a long and successful tradition of boarding, it is very often the case that too many people want to study here. All special diets are catered for. C) Our school is unique. It is a school for boys and girls aged from 7 to 18 years. Our boarding fees will be a little over &10,500 per year — that is about half what you would expect at a private school. This is a specialist Sports College. In addition to all the usual facilities for sport we have an indoor swimming pool and a Riding School. Boarding houses are organised to reflect the needs of each age group. Younger children live in Rank Weston House. Boarders aged from 11 to 13 have a separate house for boys and for girls. Older boys and girls live in Gatton Hall. All of the boarding Houses have been completely repaired in recent years. There is always a vegetarian option and other diets can be catered for by special arrangement. D) Our school is co-educational state secondary school, with almost 1400 pupils and students. About 1100 pupils between the ages of 11 and 16 study for their GCSE exams, with more than 300 students in our Sixth Form studying for A-Level exams. The school is accommodation is set around three buildings. Pupils in Years 9 to 11 are based in the main building in the town. The Sixth Form is based in the old girls high school buildings. Years 7 and 8 are based in a separate building. We want our pupils to work with business to develop our Specialist School status as a Maths and Computing College, and develop the skills to succeed in these and other fields.
