you should first apply for the counselling process by  registering yourself for the AIQ COUNSELLING and STATE COUNSELLING.

AIQ COUNSELLING :

once you register yourself , you will be given a date for CHOICE FILLING , on this date you have fill your choice for colleges in a serial manner , because the first college you choose will decide your preference, so be careful while entering your choice, and if you dont want to take any risk , choose all the colleges but in a serial manner based on your preference.

STATE COUNSELLING :

same goes for this , once the merit list is released you need to fill your choice in a serial manner and I advice you to fill all the govt colleges in your choice , in case you dont get any college through AIQ.
