Hii aspirant..

Both Techno India salt lake Institute and Maulana Abdul Kalam Azad University MAKAUT  of Technology makaut are very good colleges under WBJEE entrance examinations.

Techno India is a private college where as makaut is a government college and if we compare the fees then the fees at makaut it is  less compared to Techno India saltlake.

Infrastructure wise Techno India being a private college is always preferred.

Faculty wise obviously makaut is a government college so will be having a better faculty.

If we compare the placements at both of these qualities then the placement scenario at both of these qualities is almost same.

Location wise both of these colleges are located at Prime location Kolkata city.

Thus both of these colleges or not very much different in these aspects so I would suggest you to go according to your choice as makaut is a government college so basically in this manner it is having an upper hand .

Hope it helps. 

Best of luck.
