Hi Aspirant!

No doubt you can easily get CSE in SRM Chennai (KTR campus) easily with the mentioned rank. But as you are confused between VIT and SRM for CSE, I would suggest you to choose SRM , Chennai even if you are getting CSE in VIT Vellore campus (main campus). It is because you are getting it under 5th category and it will cost you much higher than CSE in SRM Chennai.  For the placement opportunities, I would say that both SRM and VIT offer good number of placement opportunities to students, thus you do not need to pay 5 times the actual fee of CSE in VIT.

Hope I answered your query, thankyou!
