Well the options which you have provided are one on one . All the three colleges are good .

But if i were you i would have chosen it on the interest. Interest for the subject , because whatever you chose you have to live with it. So if you like electronics andd all then you can go for nit surathkal ,you have to wait till round 5 or 6 to get it. But if you are passionate about coding then you can opt for cse in nit calicut.

Hope it helps.

Thankyou.
