As a retake student who has just finished the college entrance examination, I can offer you some experience. Last year, I didn't get admitted too, but this year I scored 18 points higher than the first-tier university admission line.
The strength of the retake class is indeed remarkable, but this is closely related to the quality of students admitted into the program. The students in our class all have a good foundation, and our school also strictly supervises the retake program. Out of 59 students in our class, more than 40 were admitted to first and second tier universities. Of course, there were also quite a few classmates who didn't perform well, some even worse than last year.
If you plan to retake the exam, you must be mentally prepared. At the beginning, many students may have strong confidence, perseverance, and determination, deciding that they will study hard no matter what this year, fully motivated.
