Hi !

If you get two colleges , you first need to cancel your admission in the first college in which you have taken admission , because the first college will take all your necessary documents , you first need to withdraw your admission and take all your documents from that college , so that you can apply in the other college.

You can choose your college , according to your wish.

All the best !
