After joining the army, you can't take the college entrance examination, because you will cancel your account in the local area after you get the army, that is, you are not eligible to register. But in the second year of military service, you can apply for the military academy. Of course it's hard.

You can go to an ordinary university. At the end of each year, the troops come to the university to recruit, and keep their school status to join the army. The treatment is much higher than that of social youth joining the army. For example, those who have won third-class merit can walk graduate students. After graduating from college, you can also choose to apply for graduate students in the army or apply for conscription in the army.
