Jabeen, your reservation or Category is only confined to India. You do not have reservation facilities or benefits while applying for Universities abroad. This is not just for MBBS but for all the courses. So, as a Candidate belonging to BC-E Category, you should score atleast 40 percentile of the top NEET score. That is the cut off. Now for studying Medicine abroad, you need to qualify in NEET. So you should scorre atleast 40 percentile of top NEET score. In 2019, it was 107-133. It changes 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. So you should aim for atleast 175-200.
