Vikas, 2021 is a long way to go. Cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam. The trend can be assumed if atleast we have 2020 admission data with us. But because even NEET 2020 is yet to be held, it is too early for predictions. But on a general note, you will need atleast 400-450 for a seat in a GMC under Hyd-Kar reservation.
