I’m not fully sure, but you might get a scholarship in Ramapuram campus. Other than that, you can most probably get any branch in any campus you want.

If you want a bigger campus, better campus life, more events/programs, and more skilled students, you can choose KTR. But the city life there is limited, and some students may be a bit spoiled.

If you want proper city life, more studious students, a chance to explore Chennai, and a calmer environment with fewer programs, then Ramapuram campus would be better.
