Dear aspirant, 

The best high scoped branch engineering is COMPUTER SCIENCE / INFORMATION TECHNOLOGY . These are both the branches which have the highest scope branch in engineering . 

But there are also other branches with the best demand in india like : MECHANICAL ENGINEERING , AEROSPACE ENGINEERING , CIVIL ENGINEERING , ELECTRICAL AND ELECTRONICS ENGINEERING .

Well without doubt CS. Everyone is rushing to occupy a seat in computer science irrespective of college. Then comes EC , which is equally in demand to CS and then Mech and EEE.

What I would like to suggest is that u should try to find ur inner passion of which engineering field suits u well and follow that. It's upto u now. Try to find the best course which suits u rather than going for a field which is in high demand. "Each and Every field has its own -ve and +ve"
.

All the best ! I hope u make a wise choice.
