There is no big difference.
make sense
1, the air force recruits two types of pilots from college students: students and graduates. The latter is a double bachelor after graduation, and the starting point is higher than that of the flight academy. However, considering the study time and other factors, there is actually no essential difference in treatment.
2, but the point is that not all college students have the opportunity to fly, so if you have a dream of flying, it is recommended to start from the third year of high school. Moreover, after all, the physical examination requirements of pilots are very high. If you can't recruit a pilot, you will get good grades in the military academy and become an officer after graduation.
