hi Shruti,

No. You would need WBJEE rank alongside NATA for the counselling. Only then can you opt for your preference in B.Arch.
NATA scorecard is mandatory during the counselling for securing a seat in the B.Arch programme in Jadavpur University.
For admission in Jadavpur University architecture department WBJEE GMR(General Merit Rank ) is necessary along with qualification in NATA. That means only NATA score is not enough for admission in B.Arch , you must appear or have had appeared in WBJEE and secured a good rank.

I hope this answer will help, all the best for the future! !
