Hi Ragul, 

In order to get a MBBS seat through NEET ug and if you are a general candidate then you need to pass Physics, chemistry, biology with 50% marks individually as well as in each of these subjects. This is the minimum requirement for a candidate to apply for MBBS seat through NEET ug. However, if the candidate is from reserved category, he or she would need atleast 40% marks in each of the subjects as well as in combined. 

Hope this helped ! All the best for the upcoming exams. Keep your calm and give your best ! :)
