Paragraph A: Answer Many people think life comes with no guarantees. However, freshers' week at university is guaranteed to be the most fun (and the most expensive) week of your life. You meet many new people (a lot of whom you never see again after the first two weeks), find your way around campus, and spend lots of money on tuition and accommodation and, of course, on going out. The purpose of freshers' week is to get all the new students registered on their courses, allow everyone to settle into their accommodation, get timetables sorted out and to receive an introductory talk from the Chancellor of the university. The real reason for most people to attend freshers' week is to have a really good time. Paragraph B: Answer Unfortunately, you have to go through with the registration and talks, or you may not be listed in course timetables, not receive a union card (essential to student life) and quite possibly have no grant cheque. For registration, find out where and when you are due to register. This information is usually sent to you in the post before you go to the university. The time you register probably depends on which course you are taking, and the initial letter of your surname. Those people with surnames A- Hare usually early-morning registration sessions. Paragraph C: Answer It soon becomes clear at the end of registration that it is all worthwhile, when you are finally given your passport to student life: the Students' Union card. This small credit card-sized ID card gets you into many nightclubs cheaply, gets you discounts at quite a few shops and fast food chains, and, most importantly, gets you into the Students' Union. The Student s' Union is where students spend most of their evenings in freshers' week. Throughout freshers' week, remember this golden rule: enjoy yourself. Do not go to the bookshop and buy all the books on the reading list with the idea of finishing them before lectures start. You do have to work when the term begins, but not during freshers' week. Paragraph D: Answer The approach to work at university is very different from work at a school or college. You are expected to do a great deal of studying outside lectures, without being asked to do it. Most degree courses have some time set aside for small groups of 20 students to meet a tutor and discuss any questions they have about the lecture, and also to go over problem sheets. It is essential to prepare for these before the classes. Each week, make a note of any problems you have understanding work in lectures, and mention these in your tutorial. Paragraph E: Answer Try to take advantage of what free time you have to the full. Using your free Wednesday afternoon (set aside by most universities as an afternoon off, for sporting activities) to play your favourite sport is a great way to relax.
