Waitlist list means that American universities tell you that your qualifications are good, but we have made enough admissions. If our registration rate is lower than last year, some degrees may be vacant. If you are willing to wait, I will come to you. For example, the enrollment quota of a university is 1 0,000. According to the proportion of last year, 50% of the students admitted will apply, so the university will send 2000 admission notices. But as a result, only 40% of the students paid the deposit this year, and 200 places were vacant. At this time, the university will consider enrolling students from the waiting list.
