When is the best time for Cobb to start contacting his mentor? I don't know where to start when I take the doctoral exam for the first time.

When you decide to take the exam, you should contact your tutor in time, at the latest two to three months before registration, because this is also the time for your tutor to select students. Contact the tutor. You can contact the interested tutor by email, SMS, telephone, QQ, etc. and ask if you can apply for his doctoral degree. The general tutor will reply to you in time, even if the tutor has no quota. However, the best way to contact the tutor is to find relevant people in the industry for reference, and it is best to visit in person before the exam.

Many benefits of early contact:

1. The doctoral supervisor may arrange you to do some daily work on existing topics, so that you have the opportunity to understand the specific direction and content to be studied during your future doctoral period. The doctoral supervisor will also indicate whether he is willing to recruit you according to your scientific research ability, which will give you a clear attitude. If the doctoral supervisor doesn't know much about you, even if he passes the entrance examination, he has a certain veto power.

2. If you don't try to contact, you may not know whether any other students are willing to study PhD in the name of PhD supervisor this year. In other words, it may be that the master's degree of the doctoral supervisor brothers has been queued for examination, or it may be that the students who were particularly interested in the doctoral supervisor last year did not pass the examination that year and will continue to take the examination this year.

3. The PhD supervisor will take you to various academic conferences and learn more about the academic prospects and trends of the discipline through the contents of the conferences. In this process, you can find the research content during the doctoral period, because this is an important content that every doctor needs to consider before entering the school.
