With 3300 rank in JEE main paper 2..which college will I get for B.arch

Hey,
You did not mention the categorg, so i assuming you are a general category student. This is a decent rank and as per the cutoff trends for last few years with this rank you have chances of getting best institutes like:

• NIT Hamirpur
• NIT Patna
• NIT Raipur

You can see last few year's cutoff on the link mentioned below.

These are just trends, cutoff varies every year based on so many factors. So it just the predictions.
Hope it Helps.
