Dr Ram Manohar Lohiya Medical Institute had the lowest cutoff in Uttar Pradesh state in the year 2018 which was 469 marks. The next lowest cutoff marks were 492 marks in U.P. Rural Institute of Medical Sciences & Research, Etawah. Rest of the medical colleges had cutoffs above these scores probably in the range of 520-590. The topmost cutoff college was King George's Medical University, Lucknow with 589 marks equivalent to an AIQ rank of 2318. So accordingly for you to stay safe scoring above 550 is must I guess to ensure your seat.

And if you need admission in other states throigh 15% AIQ then scoring above 600 is must.

To know the cutoffs of each of the government as well as private MBBS BDS colleges of UP, refer to the following website..
