College not required

We went to see training centre of arm forces. We went around and saw that they give training in everything  - like shooting, gun, parachute landing etc.

At the end of the trip one child said  "so we do not need to learn anything in the college, they will anyway give training".

This child was told that to become pilot he needs to become engineer and he needs to go to engineering college and to go to engg college he will have to work on subjects like maths and science.

now what ?
