hi Mansi 

As you have already decided to go for upsee ,it may provide you a wider opportunity both in b.tech as well as in b.arch.But keep in mind to prepare best for b.arch as there is only one or two government college for b.arch.so prepare well and give your 100%.

All the best 

Hi Mansi

Considering that UPSEE or UPTU is on April 29 for both B.Tech and B.Arch and also I am assuming that you belong to UP, your decision is right.

NATA will also be on April 29 clashing with UPTU (B.Tech) paper.

Please note that if you will appear in UPTU, you will have chances of getting admission to UP colleges only.

Hope this helps.

All the best !
