Special types of enrollment are carried out in a batch of undergraduate courses. Special-type enrollment volunteers enroll special-type enrollment volunteers in colleges and universities according to the total score of qualified candidates' college entrance examination scores, preferential scores given by colleges and universities, and the simulated investment line of colleges and universities. After determining the admission list, they will make a batch of undergraduate parallel volunteer investment files.
A batch of undergraduate admissions in Henan Province adopts the parallel volunteer model. Parallel volunteer's bidding principle is "score first, follow the will, and bid in one round".
