Hello aspirant,

It is difficult to predict because cut-offs changes from year to year and they vary from College to College. Also Caste Category of the candidates matters.

As you have not mentioned your Caste Category, so I'm considering it as General Category and providing information based on it. You need to get rank below 300 to get B.Arch in good Colleges.
