hello aspirant...

since the cutoff for the jee mains paper  have not been declared by the nta yet. you need to wait for the cutoff as there are certain nits that have increased the intake of the architecture students. well with your percentile the chances of getting admission in nits are less. you need to try hard for the next session , though you may get qualified in jee mains paper  you need to qualify in the jee mains paper 1 as well as the jee mains paper  advanced examination for writing the aat exam.

hope this helps

all the best
