I got 92111 crl rank in main. Can I get any nit or iiit's? I got -5 marks in physics. Plzz help me.

You can't get any nit/iiit with this rank . Negative marks in physics is not a problem . It matters in jee advance where you have to score more than the cutoff of each subject that is 10% . You should go for gfti colleges or for private colleges . You may get admission in nit/iiit if your home state is West Bengal,  Jammu and Kashmir or eastern states.  You can also go for csab rounds .
Hope my answer clarified your doubts.
Thank you for visit to Career360.

Hello,
You have very low chances of getting admission in any NIT or IIIT based on your jee mains rank as the cutoff of these colleges are usuay high.But you can try for admission in private colleges through state counselling based on jee mains rank.
Good luck.
