Hello aspirant,

Well to get admission into colleges for B.Arch through NATA score, you have to first qualify the exam. To qualify NATA you have to score atleast 30 marks in Mathematics and general aptitude and 20 marks in drawing. However the overall marks has to be 70. Since, you have 80 marks so you have qualified NATA. Now to get admission for B.Arch course you have to attend the respective colleges counselling process inorder to get a seat. Below I have listed some of the collegs where you could apply for B.Arch course -

Good Luck !!!!

On the basis of the marks one cannot accurately predict the college to be allotted. In order to know the avalability of the institute you have to go through the online counselling rounds and based on your marks in the entrance exam, you can get the seat in the design institute. The admissiion will be based on the NATA score and the marks in class 12. The score range above 130 can fetch you the good private institute and the score above 150 will get you the govt. institute. Here your score is below 100 so it would be difficult for you get into the college of your choice or you may not get the decent college. Also the percentage of board will affect a lot in your case. I would suggest you to go through the counselling rounds and then you will be able to get the seat allotment.
