Hi,

There is basically 2 process for admission in Techno India, salt lake, either you have to go through wbjee or jee mains rank or you may take admission through management quota.
If you want to get direct admission in Techno India salt lake you have to talk with management of Techno India.

And the fee for this will vary and it is quite high. If you get seat through WBJEE counselling or through JEE Mains the fee is 3 lakhs for the entire course duration in CSE. And you must have atleast 60% aggregate in your 10+2 from a recognised board.

I hope this help.
