there is no age limit. The conditions for university admission have nothing to do with age. As long as the results, physical fitness and other conditions meet, you can be admitted to the university by filling in your volunteers according to the process. In addition, in addition to students who take the college entrance examination, there are also adult college entrance examinations. As you can see in the news, people in their seventies and eighties take the college entrance examination every year, in order to realize their college dreams.
It doesn't matter. The important thing is that you have really learned knowledge. Having excellent theoretical knowledge will be of great help to your future work. In the future, company leaders will mainly value your knowledge and ability.
If you are old enough to go to college, no one will discriminate against you. Just be yourself and study hard. What universities value is to cultivate personal strength.
