Hy dear aspirant, 

Neet is one of the most appeared competitive exams for admission into mbbs or bds or bams or bhums or unani.

As per your details, your marks really less to get admission into cmc vellore as its one of the most popular medical college which students preffer to get in. 

With 222 marks only in neet ug its difficult to get but as you have special category to apply for than you must try for it though the fees demanded will be very high but if you can afford it, you must try . Your chance to get in bums will depend on seats vacancy, no. Of candidates applied. 

You can sit for counseling and give a try to it, but if you don't get better try for next year, you might end up getting mbbs in a good government college with low fees. 

Hopefully you can get what you want. 

Good luck
