You have got a decent rank but it may be difficult to get admission.

Ranks below 7000 can get any branch

Ranks > 7000 and < 12000 can get ECE, EEE, E&I, IT, Civil

Ranks > 12000 and < 15000 can get IT, Civil, Production Engineering

Ranks > 15000 can get Bio-Informatics, Bio-medical, Biotech

You are just a call away from getting direct admission in VIT in your desired branch.

You should go for VIT,Vellore rather than Chennai campus.

VIT University, Vellore is best as it provides best and advanced courses.
