Dear Akansha Saxena,
Your NATA is good enough. I think your 10+2 mark will be good.So, surely you will get IP University. Let's hope for the best. Wish you all the best!

If you cross the limit of 70 marks, then you will be able to apply for architecture colleges.
You will definitely get any of the architecture colleges in India.
If you tell me your exact NATA score and class 12th marks, then I will be able to counsel your college and predict which college you might get.
If you like my answer, then raise your hand up by making an up vote.
All the best for your bright future.
