如题，收到了BU的邮件【Invitation to chat with a current COM student】
邮件内说：
The purpose of an online chat is to discuss applicants’ interest in the program, COM and Boston University and determine fit. Chats will range from 10-15 minutes in length and provide the applicant an opportunity to ask questions about coursework, faculty and the graduate student experience at COM.

The chat is not an admissions interview, but an opportunity to discuss the program further with a current student.
This chat is not a time to discuss your admission decision, scholarship or I-20 paperwork.

想请问下各位这个是必须参加的吗？谢谢！
