depends upon how much percentages you have got in 12th + decent NATA score.
Actually admission counseling is based on 50% of 12th percentile & 1/4 th of NATA score.
It also depends on ` you are from inside or outside of Delhi.

I had 137 at NATA & 84% in 12th.
Unfortunately i missed it by just 1seat. I was from Outside.
Good luck!!

Minimum NATA score should be at least 100 for getting admission into any architecture college. It is not mandatory that you should have at least this much of NATA score to get into USAP. It depends on your over all aggregate.

Hope you understand and gopd luck to you!
