Hello aspirant,

Well there is no centarlized counselling process for admission into B.Arch through NATA score. The candidates have to attend his/her choice of colleges counselling process and apply for B.Arch course through their NATA score. Now to get admission through NATA, one has to be NATA qualified and for that he/she has to score a minimum 30 marks in mathematics and 20 marks in drawing but the overall marks should be 70. Since you have 90 marks so you are NATA qualifed , so you will get admission into a college for B.Arch course. Below I have provided a list of some colleges where you can apply for B.Arch course - 

• Dayananda Sagar College of Engineering
• Ramaiah Institute of Technology
• Manipal University
• Techno India University
• Chandigarh University
• KIIT University
• Hindustan Institute of Technology and science

These are some of the colleges where you can apply through your NATA score to get admission.
