I hope you would have a shining future ahead.

Dear student, you won't get any problem in BITS Patna on the basis of that it is not approved by UGC but approved by AICTE. These are two different bodies governing undergraduate courses. They are well recognised all over India, the difference only lies like in CBSE and ICSE.
