Hello Kishan,

It is difficult to predict your exact admission possibilities for any college or the exact qualifying marks as the exam is being conducted twice in multiple session, The final NTA scores will be used to rank the candidates.

You can use this formula to calculate your expected rank-

874469 are the number of candidates appeared for the January exam. So rank formula is (100- your total score) * 874469 / 100.

If the number of candidates for April exam increased to 1400000 then your final rank shall be (100- your total score) * 1400000/100

You can also check your admission possibility with the given below JEE Main college predictor.

Moreover your catagory will play a major role in your selection.

If you belongs to OBC or SC/ST you can get admission in NIT's.

Hope this helps.
