First of all i guess you must be knowing this that Techno India University is deemed university and Techno India Salt Lake comes under WBUT.

The fee structure in TIU would me somewhere near 50k per semester and in TISL it be would be comparatively less.

In both the colleges you may take direct admission but the seats in TISL is comparatively less as compared to TIU.

The placement record for both the college is same as both comes under Techno India Group.

Personally speaking the level of BBA in TIU is increasing from the time GAGAN PAREEK sir became the associate dean .
