No,you cannot get admission in any college of architecture without appearing in NATA.
NATA is a compulsary exam to get admission for the 5 yrs B.Arch course across india.
But there are some state universities where you don't need your NATA score instead you have to clear the state entrance exam.
The other good option is that you can appear for Jee mains paper 2 through which you can get admission in different NIT's and other colleges.
BITS MESRA,Ranchi is a decent college where joining architecture will be a good option.
Hope it helps!
