Two types of voluntary confirmation:

First, online confirmation. After submitting the volunteer, you can log in to the system again to modify the volunteer, but you must finally confirm it online within the specified time. Once confirmed, it cannot be changed. If you don't confirm, volunteering is invalid.

First, it takes effect immediately after online submission and cannot be changed. This kind of volunteer requires students to go back to school and sign the printed paper volunteer form for use as candidates' volunteer files. The significance of signature is more about the determination of legal responsibility. If you have any questions about the admission result, the final legal evidence is this paper. Failure to sign will not affect the normal admission results. Just give up the evidence that there are problems in the admission process and claim your rights. If there is a problem with the admission to the provincial examination institute, don't look for them.
