As a reflection of the sheep mentality, the majority of engineering aspirants can be seen running after CS or IT. However, I will suggest you also give preference to your interests first.
Electronics and Computer Science Engineering is a recently launched branch at KIIT and is actually great. Not many batches have passed out yet, but the branch seems promising like any other branch at KIIT.
In all, Electronics and Computer Science Engineering is a decent choice especially if you are interested in the field. However, if you are still aiming for CS, then you can opt for a branch change after one year. The cut-off for branch change is 8.5 CGPA but to get into CS you will need around 9.2+ and 8.9 or more for IT.
