Hello shrey ,thanks for asking this question on this platform.actually choosing branch for engineering is really a tough task .firstly try to get the basics knowledge about all the branches in which you want to pursue now also see the job offer after graduation in that branch then you will able to choose anyone from them .thanks 

This all depend son your interest and passion and choose what sounds mpre exciting and where you can deliver. 

As of npw CSE and ECze have huge scope and is having highest cutoffs and is most preferable by studnets. Job opportunities also great in both of them and sees an exponential demand.
