In fact, even fewer people went to college after 5060. On the contrary, they are older and have more college students.
Born after 80, I feel very obvious about college students' enrollment expansion.
Enrollment expansion began around the new century ~ ~ Many 80-year-old brothers and sisters have great difficulty in getting into universities.
By the time the college entrance examination for peers takes place, they are basically ordinary universities, and the admission rate of more than two books is close to one fifth.
Later, there were more and more books. Judging from the admission rate, the general gold content may be close to the two books of 10 years ago and the specialties of more than 20 years ago.
So,
When you use more than one book, it may be more reasonable to post-70s technical secondary school or above.
