Hello candidate,

For getting an All India Rank in his/her category of under 50,000 in the JEE Mains examination, the first thing which comes into play is the Category of the candidate.

Secondly, other factors which determines your category is the difficulty level of the paper, number of students appearing in the shift, and the cut-off determined for your particular shift. So, it's very hard to determine the exact mark for getting 50k rank but on a General basis you should score atleast 160+ Marks.

Hope you found it helpful!!
