Hi

This is difficult to make prediction as  cutoff  depends upon various factors like :-

-----------) number of students/ candidates  that appeared in the  jee main exam,

-----------) number of available seats,

-----------) performance of different students in the examination,

-----------) the branch you want,

-----------) the category you belong etc.

But yes,

When we go through previous year trend then

With 5 lakh rank,

Your chances in good colleges like NITs, IIITs , gfts is  low, you have chances in average private colleges.

Some of the engineering colleges in which you hold a good chance on the basis of past year closing rank are listed below along with the link for their previous year cutoff :-
