I got 91 percentile in mains can I get seat in lnmiit jaipur

91 percnetile means your expected rank would be around 78,210. And if the number of candidates in September Session increases then your rank would also increase. Now the cutoffs depend on various factors and you haven't mentioned your category. So considering you as a general category student and going by previous years cutoffs, CSE seats in LNM Institute of Information Technology get filled within 30000 to 40000 rank. And based on your rank it would be difficult to get CSE there. But other branches such as Electronics and Communications Engineering and Mechanical Engineering have comparatively lower cutoffs than CSE. At this rank, you have chances to get ECE there as the cutoff percentile lies around 91 to 92 for ECE. The cutoff for Mechanical branch is even lower.
