Hello,

It is difficult to indicate the exact score as the cut off changes every year. The marks rank trend also changes every year. Analyzing the previous year cut off you need to secure a rank below 6000 (EWS category rank) to have decent chances of getting seat in NIT. To secure such rank you should aim to score minimum 200-240 marks or above in JEE Main. To check the previous year cut off you may visit JoSAA website and check

Cut off is subjected to change it may increase or decrease depending on the total number of candidates applied, difficulty level of examination and total number of seats available etc.
