Vellore

No option to change branch.

You can get any branch in VIT-Chennai campus.
For Vellore also, you can get most of the branches (maybe except CSE).
Yes, you can also get ECE in Vellore.

VIT, Vellore is better than Amrita, Bangalore as in VIT there is tie-ups with many companies and also some companies have their research incubators where students go for the workshops regularly.

No doubt that the VIT is the best college it has good incubation center and many research laboratories but the main problem over there is the fees problem that everybody can't afford.

No. You can't get admission for M.Tech. You need to pursue BE or B.Tech degree first.

There is an exam called as VITMEE, which you can give irrespective of whether you have appeared for GATE. The forms are out already on vit.ac.in

Let me tell you one thing, only core NIT's have good placement all other are also fine, but not as good compared to VIT University, because VIT University offers good placements in CSE, IT, ECE branch and as compared to NIT Durgapur. Chemical branch is not up to the marks, because in the end branch does matter, so it is better to take VIT.

Hi Gunjan, FFCS system sometimes helps when we need it the most i.e. last date to submit the assignment. It's not about effectiveness but through this system you can see your marks grades and attendance leaves etc. It's for this purpose only. Some teachers in VIT are good and some are bad as in every other college in respective of explaining concepts but let me tell you this in VIT from second semester you have to choose your own faculty that's the good thing about VIT. There are lots of cooperative and good teachers in CSE as well as other branches. Hope this helps.
