Software Engineering

The average salary package for software engineering courses at Ramapuram campus of SRM University will be around INR 3-5 lakhs per annum, which will be the same as that of the main campus.
You need to be skilled enough to bag more salary packages.

I'm a student from NIT Warangal. The average package that is given by a software company in our college is around INR 5 LPA (lakhs per annum), and it varies in different NITs.

This is not same as always and changes according to the requirement every year. Sometimes you might get this in first category or sometimes it can be in third as well. But this time it seems you can get in second as the seats have not been fixed by VIT.

You should opt for B.Tech in CSE/software engineering after your diploma. If you don't want to do B.Tech, then you should start from today. Try to learn basic concepts through YouTube and then study in detail.
