Hey bijly,

Let me clear you a thing that no branch of any field is bad. Every branch has scopes all around the world in every corners. So put this out of your mind and pursue the field you have interest in or which suits your mindset.

If you go by the public, CSE branch is considered the best. But it is onto your excellence on making a branch great or worse.

Cheers!!

Hii.
As per your question, no branches are bad.
It's on your interest which you want to pursue during the graduation.Different branches has there different applications in the today world.
Nowadays students try to say some branches not good based on the placements and career opportunities in that branch, but the reality lies behind the person who is persuing degree in that particular branch who enjoys it and has full Interest in it.

All the best.
