Which course is better among computer science engineering and Bachelors in computer science?

I will suggest you to go for BE than B.Sc because the rank of BE is very high compared to B.Sc and you get lot more opportunities in BE as well you will be placed in a good company with good salary.

B tech is much better.

Go for B.Tech and focus on sharpening of your own skills.

BTech CSE is the best educational qualification to become a software engineer. It is a superior degree in comparison to BCS with wider and better scope and opportunities.
