In the transfer notice or registration information issued by colleges and universities, candidates will be required to provide voluntary institutions.

In transfer registration, the selection of students for re-examination is not strictly based on the results of the initial examination, and high-level undergraduate and voluntary colleges are often popular. In applying for majors, some majors are not common among colleges and universities, and the adjustment is more limited by one major category. Even if it is a big category, there will still be restrictions. Therefore, listing volunteer majors is conducive to the screening of colleges and universities.
