香港大学的Clearing Round是什么意思?

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.
