Today, I’m going to give you an introduction of the orientation schedule. There are two parts of the orientation next week. The first part is the campus tour. Next Monday, we will begin our tour with an introduction to the Student Union. So please gather at the door of the Student Union at 9 o’clock. After visiting the building, we will help all students to apply for the student union card. So please take one passport photo when you attend the orientation. After lunch, we will visit the library at 2 p. m. A lecturer at the library will give you an introduction about how to apply for a library card, how to borrow reference books and how to use the facilities in the library. As you know, you will spend lots of time in the library for your future studies, so the introduction is very important for you. All students can get a username and a passport. You can also register your laptop in the centre if you have one. After lunch, the next station is the Sports Centre. I am sure you will all be very excited about our facilities. There are also many different societies. You can join in any of them according to your interest and apply for membership.
    The second part of the orientation is course arrangements. You should gather in the auditorium in the west campus in the morning on Wednesday. The course coordinator or office staff of your faculty will introduce you to the course requirements. You will get some information and requirements about the compulsory courses first, and then the optional ones. Students usually get one or two days to make a decision of the optional courses. Of course, I know nearly all students will focus on the assessment. As usual, we have four considerations in the assessment. Attendance is still the first one. We expect at least 80％ attendance. And then, all students have to do assignments such as an essay. Your personal tutor will give you some help in topic choice, structure, data collecting and time arrangement, so don’t be worried. As a member of the business faculty, all students have to make presentations, especially group presentations in which you can train and improve the team spirit. The last one is the exam. I know you all hate it, but you have to attend some exams. Most exams are open-book. OK. Thank you for your listening.
