Hello Aspirant,

The cut off for jee mains /advanced depends upon certain factors such as number of candidates appearing in the examination previous year cutoffs and difficulty level of the paper.

So, one can't predict the exact marks so you need to give your best for jee mains to clear the cut off and let me tell you that clearing the cut offs doesn't mean you can get into a decent college. You need to get really good marks to get into NITs.
