Do you need to contact your tutor before the postgraduate re-examination? Do you need to bring some gifts when you go to find it? thank you

It is necessary to contact the tutor. You can send an email to the tutor first, and then send a text message to the tutor to remind you to check the email (the content of the text message is a compressed version of the email). Probably just introduce yourself, just like writing a resume, write everything you can and mention that you really want to be your disciple. The email should be very formal. If the teacher ignores you after waiting for a few days, just pick a suitable time to call him directly. If the teacher likes you, some tutors will hint that he is willing to take you, and some tutors will not say. If the teacher likes you, it may be helpful in the second interview, but it doesn't have to depend on the specific situation of the school and the tutor. In a word, contact is better than no contact. If you want to bring some gifts, you can ask the graduate students in their school to see if the tutor has the habit of receiving gifts. You can give anything that others give you, no matter how expensive it is.
