留学申请里面的 admission round是什么意思，那这个表格中的main又是什么意思

What are the differences if I apply for the programmes in the "Main round", "1st clearing round" or "2nd clearing round"?

If you have missed the main round application deadline, you can still apply for admission in the 1st clearing round. And similarly, you can apply for admission in the 2nd clearing round if you have missed the 1st clearing round deadline.

You may wish to note that we have a quota for admitting MPhil and PhD students each year and applications are considered in batches.

The main round application is the first round in which departments consider applications for the coming academic year. Normally, if there are places left after admitting the main round applicants, the departments will consider applications received in the 1st clearing round (and subsequently the 2nd clearing round) to fill up those places. Hence, you are encouraged to apply as early as possible as the number of available places in the main round will be more than that in the 1st clearing round, which in turn will be more than that in the 2nd clearing round.
