Hii Yaman 

VIT UNIVERSITY is one among the pioneer institute in india. 

Talking about the VIT rank. It has been observed that from the three consecutive year VIT is under top 20 Universities across india in various domain like Engineering, Universities, Medical , Management etc. These ranks are valid which is given by the MHRD ( Govt. Of India) innaugrated by NIRF .

I think University/ College repo or rank is more important than branch rank and till now Govt. doesn't announced any sperate branch rank till now for any College.

All the Best
