NATA

Considering your NATA and JEE Mains paper 2 there are zero chances of getting admission in any government college for B.Arch.
However, you may get admission in any private university/college with your score.

Colleges like SPA-D, NITT are better for B.Arch in my opinion. However, the college that you have mentioned are also good.

Hi,
How are you?
Well, other than IITs and NITs, there are many private universities like:
VIT
SRM
BITS
Galgotia
NIRMA University
UPES Dehradun
AMITY
SHARDA
LPU
which are having high placement records and the decorum here will make your personality development.
For you, SRM Chennai will be best.
Thank you and keep asking.

Yes, there are slim chances for you to get admission into USAP for B.Arch with 108 marks in NATA as 90+ marks are considering for admission in B.Arch colleges.
Also, you have benefit of having OBC quota. It will help you to get into USAP.

The chances to get any govt college with just 99 marks are slim.
Still, I suggest you to apply for counselling of govt. colleges. You may get any prestigious college for B.Arch with 99 marks.

IPU intakes students on the basis of merit list of IPU-CET. They do not consider the marks of JEE Mains. So, you'll have to try for other colleges. Your mains score is quite good so you can try for other good colleges. Try for NITs and IIITS.
Good luck.

VNIT is a prestigious institute of the country and attract top rankers. So, it seems quite difficult to get into it with this score. Moreover, if you have a state quota or some category reservation that might help you fetch a seat, else it seems quite difficult.

There is no compulsion for you to sit for JEE Advanced. You can attempt only for AAT to get a seat into one of the IITs for B.Arch. You should have cleared your JEE paper 2 and have a percentage of at least 75% in your 12th.

There are very less chances of you to get admission in colleges for B.Arch as your JEE Mains score is very low.
However, you may get admission in colleges that accept NATA score because few colleges consider a score of 90+ in NATA to give admission.
All the best.

Sorry dear but admission in good colleges for B.Arch are considered at 90+ marks in NATA. You have missed the required marks by 5.
So, try for any private college for B.Arch that can give direct admission.
All the best.
