2. The teacher doesn't lecture very fast, but it is necessary to take notes, because you can't guarantee whether you listen carefully in class. After you take notes, you can review them after class. Sometimes the exam is the content of the notes, especially what the teacher focuses on. Never change. Going to the library more often in class can improve your learning ability in a quiet environment. But in fact, as long as you listen carefully in class, you can hardly fail.
3. The earliest class in college is eight o'clock in the morning, which is also commonly known as morning eight. Compared with high school, it is really easier, but universities do have early self-study. In some universities, self-study in the morning is around six o'clock. Actually, it's almost as tired as high school. But not every day, so don't worry.
