2. Read the tutor's papers and explain your understanding to the tutor.
3. It would be better if we can think about the direction of future research in advance, and the tutor will also appreciate students with ideas.
Extended data:
Be sure to meet before the second interview list comes out, because meeting again after the list comes out is easy to cause some misunderstandings and have a bad influence on the tutor. Usually the tutor won't meet at that time, but he can keep in touch by email.
Before meeting, you need to read your tutor's introduction on the college website, such as his age, where he comes from and the articles published by his tutor in recent 10 years. You can know his research direction through the article. In view of this direction, I draw up a 500-word postgraduate study plan, so that the chat after meeting will be more in depth and level, leaving a good impression on the tutor.
