College students are basically 18, 19 years old, undergraduates are 23 or 24 years old, and graduate students are 2 to 3 years old, that is, they are 25 to 27 years old after completing the exam this year.

If the entrance examination for postgraduate entrance examination is repeated all the time, or if the undergraduate course is a five-year program, or if you have worked in the middle, it will be even bigger.

There are 28+ and 30+ in our college.

Hope to adopt the answer.
