Software Engineering Scope

It's the only thing engineers gets after completing the course. You want to take that too? ;) :D

BE in CSE is much better than B.Sc in terms of placements, course coverage and popularity. BE in CSE is a clear choice.

for cse u should have pcm in 12th with pcb u can not apply for any stream of enginerring

See,In engineering there is no degree like software engineering and hardware engineering.
If you are studied for the computer engineering or CS also then you should have to cover entire syllabus because it is design in that fashion, After the completion of degree If you are good in programming then you will be considered as software engineer,and if you are good in Networking and Hardware then you will be considered as hardware engineer.
In today's era Software engineer is in full demand but for that you should have to develop your programming skills,also do some certifications

B.E in CSE is best.no matter u do B.E or B.Tech there is not much difference between B.E and B.Tech.B.E will be more theoretical and B.Tech will be practical.

If you want to make career in software engineering with commerce stream after 12th, you may pursue BCA / MCA degrees. You will not able to join computer engineering stream with commerce stream.
Software engineering projects also requires business analysts for application development and support. You can also make career as BA after commerce graduation/ post-graduation. Lots of BAs have progressed to become project / program managers in IT industry after few years of experience as BA.
