Cut offs keep changing every year depending on your Category, number of students who wrote NEET, number of students who qualified, highest NEET score and difficulty of the exam. 510 marks got a seat in Coochbehar Government Medical College in State Quota via OBC Category reservation. For 2020, you should target atleast 550 and more. Because the cut offs might be higher because of higher competition. 550 will atleast help you with a seat in 2nd round of Counselling.
