Hi Maam
According to last year cut offs, some of the colleges that your son can get are:

• Post Graduate Institute of Dental Sciences, Rohtak
• Shaheed Hasan Khan Mewati Government Medical College, Nalhar

These were the government MBBS seats he can get but other than these he can also apply for govt. BDS and private medical seats
Cut offs just give a rough idea and changes every year according to difficulty level of neet, no. of applicants and no. of seats.
You can also predict your college by entering required details in the link given below:
