It gets you up in the morning. You meet your friends at the lectures. The exam questions are usually based on the lectures. Some lecturers are quite entertaining and enthusiastic.
Enthusiasm is infective.
This means that you get overloaded with information and can remember very little of it. It helps if you can edit your notes each evening, indicating the key facts and ideas. Other lecturers put their lecture notes on the web. The evening editing of your lecture notes and looking things up in the text book helps you remember the essentials. This knowledge will be useful in tutorials and seminars.
