Hello ,

For addmission in B.Arch , colleges generally ask for 50% marks in 12th PCM and a valid score in NATA. Talking about the top universities , they consider a ratio of 50:50 of 12th and NATA score. 

Considering your score , you have pretty good score in 12th and also a fair score in NATA. For the highly top ranked colleges you need 130+ score in NATA. But you can apply for the government colleges and also for the average ranked colleges. If you are from state board , you will easily be able to apply in colleges of your state , they have some 50-75% reservation. If other boards , you might face some difficultly but your score is enough to get addmission in a decent college.

Hope this information was useful. All the best.
