Is it possible for me to pursue regular B.Tech along with B.A from IGNOU?

Dear Piya, To the best of my knowledge and research, I don't think pursuing two degrees together and simultaneously is allowed. However, one can opt for a diploma/ certificate course. For more, you can refer to the below article https://www.shiksha.com/now-pursue-two-or-more-programmes-together-a

Yes , you can go for BE or btech course.
