You need to qualify in NEET if you want to study MBBS abroad. That will be the least score that you need to score. You haven't mentioned your Category. Neverthless, it is 50 percentile of the top NEET score for General Category and 40 percentile for OBC,SC,ST. Now going by these, in 2019, the cut off range for General Category was 134-701 and for OBC,SC,ST it was 107-133. Now 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. Now you will have to score atleast 150-160 depending on NEET 2020 cut offs if you want to pursue MBBS abroad.

Hello...Hope you are doing good...at first you need to qualify on NEET exam...and to get a chance to persue in abroad you need to score above 500 marks out of 720...hope this will help you...best of luck for your future.
