JEE Main

dear you must also mention your category then only we can discuss whether you can take admission there or not.

Prospective applicants desirous of taking admission to First year of undergraduate course in Architecture (Bachelor of Architecture) in India take NATA. NATA scores are used by admissions authorities of different Government, Govt. Aided & unaided schools / colleges of Architecture, to provide common measure for comparing the qualifications of applicants, for admission in addition to their scholastic performance in 10+2 or equivalent examination

First of all congratulations on securing such a good scoring. You may get a seat, depends on the higher ranks submitted, here is a link for all approved architecture colleges across India - https://www.coa.gov.in/index1.php?lang=1&level=0&linkid=25&lid=26

you need to first check your rank, which is coming on 23 june. then you must check last year's cutoff, and check which college best fits your rank.

at most 3 attempt at year of 12 passing

No it will not be possible. you rank would be around 50k which is not sufficient for getting ME in NSIT. ME closed at 20k last year so it would not be possible to get admission for ME.

Assuming you are a delhi student you can get anything in nsit . best of luck

Yes 75% or your percentage should lie in the top 20 percentile of your state board
