After missing the campus recruitment in the second half of the year, will there be recruitment in the first half of the second year, probably in what month?

Generally, colleges and universities that attend in the second half of the year will not go in the first half, and schools that did not attend in the first half are recruiting. Unless the recruitment is far from the target value, the second recruitment will be carried out, usually in March-April and before May. Generally, it depends on your major, and fewer people change their major.
