Sir I m getting 535 marks Rank 30728 Can I get govt college from AIQ ?

Hello,
You have not mentioned your category anywhere ,ao I assume it to be genral.
If I consider the previous year data.then your chances of getting admission in a government medical college are moderate.if you have domicile of any state then it might help you to fetch a government seat in that state  through state quota .
Browse the link given below for much more detailed information. http://www.google.com/amp/s/medicine.careers360.com/articles/neet-cut-off
The cutoff changes almost every year,so not much can be predicted .cutoff depends on the difficulty level of the paper and the number of students who appeared for the entrance exam.
Just hope for the best

Hiiui....
Yes, it is a quite good score to be in the merit for private medical colleges.

The NEET cutoff 2019 candidates belonging to UR category have to score a minimum of 117/720 marks for qualification in NEET medical entrance exam. The OBC/SC/ST category candidates need a minimum of 96 marks to qualify NEET 2019 exam. NEET 2019 will take place on May 5, 2019, in a single window offline mode.

Thus getting 500 will land you in a good college. If you can score 500+ then there will be high chances that you can also apply for deemed universities and colleges.

All the best:)
