my category is NT -b may I please know how much marks do I require to get admition in jj medical college for mbbs???

We do not have 2019 data yet. Neverthless, NT-B falls under Regional Quota in a broader spectrum of Maharashtra Reservation. In 2018, under State Quota, for 70% regional, 503 marks secured a seat in JJ Medical College. Now this is 2018 data and 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. For 2020, you will need atleast 575 for a seat in this College. For guidance during admission and counselling, you can use our MBBS Companion:  https://www.careers360.com/mbbs-companion
