Hi there,

Firstly every engineering department has the same amount of hard work to do,

Secondly it totally depends upon your skills and interst, if you know coding and technical stuffs then circuit  branches like cse, even, electrical would be easy for you, if you know more about chemicals and it's properties then chemical and metallurgy is good for you,

If you can do ground works easily then civil and mechanical are easy for your.

It all depends upon your knowledge and interest.

I hope this help
