Personal choice
Repetition is the right of every examinee. Maybe I didn't try my best in the first exam, or I was dissatisfied with my grades, so I chose to challenge again. This is their expectation for the future and their persistence in their dreams, not the occupation of educational resources.
resource demand
Returned students really need teaching materials, teaching AIDS, remedial classes and other resources to prepare for the war. But this does not mean that repeating reading is an occupation of educational resources. On the contrary, the supply of resources to meet the needs of repeat students can help them improve better, and at the same time create job opportunities for the preparation and counseling industry.
Social welfare
Some repeat students have not only achieved personal success, but also played a positive role in promoting social development through their efforts to enter ideal universities and majors. Their higher education, skills and quality will inject vitality into society.
