Architecture

you should have patient.
even better nit may confirm. till 3rd round

don't worry.
admission in nit Patna is confirm.
even you have better option like nit jaypur and hamirpur. till spot round .
you should have patient.

there are total 5 attempts of nata in a year.so your year will not be wasted.if you are unable to clear first time.then try again.all the best :)

You need to be in 10% cut off bracket ,
SPA delhi is best institute for architecture and for best you really need a good score. in my opinion you need to score 250+ for guaranteed admission in architecture but 215 would be enough for admission in planning branch.
But with these marks you will get selected in the spot round only. For admission in first round you need a score of 290+.

You have to give Jee main paper 1.clear advance and again appear for AAT(Architecture aptitude test)

Till date only two IITs offer Architecture. IIT Kharagpur and IIT Roorkee

you need to give NATA exam again as 80 marks is minimum criteria

You may suffer problem in Placement as your marks are below 60% bt as u r going in defence its ok.

For B.Arch u can go through NATA, Jee main paper 2(NITs and SPAs) and AAT(for IITKharagpur,IIT Roorkee)only.There is no need of giving colleges entrance exam
