Hi Irshad!!! Congratulations on both of your ranks!!! As you asked according to your rank so I would consider cutoffs of last few years so I would say you should go for SRM University as you would surely get IT in the main campus as cutoff is close to 20000 with slight chances of CSE as well in the main campus where cutoff is around 10000 and sure chances of CSE in other campuses whereas in VIT there are hardly any chances of getting core streams in both vellore and chennai so I would suggest you to go for SRM

Hope that helped.Thank you
