Hello aspirant,

The cut off changes every year depending upon various parameters like difficulty of exam, number of students appeared, number of seats available etc.But the cut off for SC candidates will be somewhere around 40-55.So to qualify in JEE Mains you need to get minimum marks.But you should score above cut off marks to increase the chance of getting a good college and branch of you Choice.However, cut off is subjected to change it may increase or decrease slightly.You need to prepare well.I hope this is helpful to you.
