if you have keen interest in computer science then you can come here at iit delhi or iit bombay or iit madras

and no matter which branch you are in

yyou can always do a minor area in computer science which consists of approx 9 cs courses to choose from

no doubt the brand name of iit is very good but if you have a strong disliking for a particular branch then please don't join it because then your academics will suffer

bits pilani is a very good option so you can consider joining it also
