What does it mean for the tutor to reply to me after the postgraduate entrance examination and re-examination?

The reply means to show you that he has the position of doctoral supervisor, and then look at your specific strength. You are welcome to apply. If you pass the exam, you will be considered as his student.

It is normal for tutors to reply to the doctoral exam, so the best way is for teachers who are interested in each other to ask if they are free to meet, but don't be forced. After all, some teachers are just being polite. On the issue of choosing a teacher, it's best to cut the gordian knot quickly and don't entangle.

Cobo, note:

First of all, we must carefully choose our majors and tutors, and we must choose the majors we are interested in. You can't just study for a diploma. Studying for a doctorate is a painful and long process, and an inappropriate major will make this process even more painful.

Secondly, contact your tutor before the exam to confirm his intention to admit you. Don't think it's ok to get in touch only after getting a high score. The number of tutors is limited.

Finally, strengthening your English, especially reading and writing, is the focus of the exam. If English crosses the line, the tutor is willing to accept it, and professional courses are not a problem.
