Hi. The procedure for admission into any semi government college is same as that of admission into government medical colleges of a state. This is:

1. You will  have to crack the NEET exam with very good marks. After the announcement of results, which is done a month or so after the exam, you will have to apply for state or All India counselling.

2. The procedure differs for state and All india counselling. 15% of all the seats in all medical colleges across india are reserved for AIQ (all India quota). The rest 85% pertain to the state. The same state counselling authorities which conducts the counselling for state quota seats conduct the counselling for private colleges as well as for semi government colleges. The counselling may be conducted at the same time.
