Going to graduate school at the age of 26 is considered old. Age is not a problem, no matter at which age you want to continue your studies, you can do it as long as you make up your mind to work hard.

If the answer is no, it is obviously not what the professor wants. You can ask the professor about his recent research results to show your concern for the professor and his professional research, and show that you have come prepared, not to cope with the exam. This relaxed and impolite answer can help you get a higher impression score.

Attention to graduate school:

The professor hopes that you can have a deeper understanding of the school, and it is also necessary to do your school homework in advance. It is suggested that with the help of the tutor, we should have a thorough and detailed understanding of the tutor and his research. From a professional point of view, it is necessary to cite some viewpoints of professors to prove yourself and sincerely express your willingness to apply.
