In 2018 under State Quota, 469 marks secured a seat in Dr. Ram Manohar Lohiya Medical College. That was the cut off. In 2019, 580 was the cut off. So this is a prrof that cut offs chamge every year. Private Medical Colleges do not participate in All India Counselling and the seats are filled through State Counselling alone. And for appearing for State Counselling you need to hold the domicile of that particular State. Or else the only other option is through Management Quota. Under All India Quota, All the 15% of All India Quota Seats except for Jammu and Kashmir, 100% Seats at Deemed and Central Universities, IP Quota seats in ESIC Colleges, Seats at AFMC, AIIMS and JIPMER are filled by DGHS. The 85% State Quota and Private Colleges are filled by the respective State Authorities. And there are 3 Categories in Private Medical Colleges. Category A is the Government Quota Seats. And only candidates of the home State are eligible to apply for these seats. B Category seats are also called Management Quota Seats and they are filled through State Counselling and the remaining seats are fileld through direct Admissions by contacting the College directly. Here the fees is usually nothing less than 40 lakhs. The last Category is NRI seats Category and you cannot apply for that. So coming to your question, if your son might only score 400, no disrespect but the chances that he might get a seat through Counselling are less. So the only option is to wait until all the rounds of counselling are completed and then apply for direct admission.
