Read the passage carefully and choose the correct answer.

 If you want to go to a university, you usually apply during your last year at school, when you are 17-18. You can apply to study at any university in Britain and most people choose a university that is not in their own town. So, university students usually live away from home. Students get a grant from the government to study. At the beginning of your last year at school, you receive an application form. On this form you choose up to five universities that you would like to go to. The form is sent to those universities with information from your school about you and your academic record. If the universities are interested in your application, they will ask you to attend an interview. If they are still interested after the interview, they will offer you a place. Any offer, however, is only conditional at this stage. Applications and interviews take place several months before students do their A-level examinations. These are the exams that you do at the end of your time at school. So, when a university makes an offer, it will tell you the minimum grades that you will have to get when you do your A-level exams. If you don’t obtain those grades then, you will not be able to get the place. It will be offered to someone else and you must apply again to another university. You don’t have to accept your place immediately. Some students don’t want to go straight from school to university. So, after they have taken their A-level, they take a year out to work or travel.
