Every year during the college entrance examination, every candidate and parents must pass two checkpoints: the exam and the volunteer. If the exam is only a candidate in the exam room for a person's intelligence, then the voluntary pass is the embodiment of parents, children, relatives and friends and other collective efforts. The exam is difficult, filling in the volunteer is more difficult! The score is high, worried about low losses; Scores of medium, worried about the high failed; Those with lower grades worry about not learning in the end. In this regard, this work analyzes in detail the content of college entrance examination voluntary filling in from the aspects of basic knowledge, skills, influencing factors, cognitive misunderstandings and risks, and action courses, etc. Finally, it introduces students' cognition after graduation, hoping that this work can provide help for more college entrance examination students' voluntary filling in.
