Even so, I think it is better to prepare a resume than not to prepare it at all. Once you enter the second interview, you'd better contact your intended tutor first. The purpose of contacting the tutor is to let the tutor know about himself, and then impress the teacher with the intention of enrolling himself. The best way for a tutor to know himself is an academic resume.
The production of academic resume is different from work resume, which focuses more on academic qualifications, scientific research experience and academic achievements. For undergraduates, scientific research experience and academic achievements are weak points, so it is necessary to highlight university achievements and list courses that match the research direction of intentional tutors and their average scores. If you have a graduation project, write down the theme and include it in the column of scientific research experience. Mastered skills, such as English ability and experimental skills, are all factors that can impress the tutor.
So it's best to prepare your resume and contact your tutor before passing the second interview for the first time to find opportunities for further communication.
