With a JEE Main Paper 2 rank of 6624 and 89 percentile in the General category, you have a decent chance to get into some government colleges for B.Arch or B.Planning, especially in newer NITs or centrally funded institutes. Top NITs may be difficult, but you can still get a seat in lower or mid-tier government colleges. Keep an eye on opening and closing ranks during counselling. Fill many choices and stay flexible with college and branch options to improve your chances.
