Dear Candidate,

You should go for Kalani govt college only from fees point of view because  it is govt college so fees will be less which is good point if you comes from middle class family but coding is not good in this college,also placements are not so good. On the other hand, IIIT kalyani is fairly newer college wihich has 9 0000 tuition fees of 1 semester which is very high and also there is only CSE branch & no separate IT branch  so it is more focused on CSE and it has good environment for coding and have decent placement records .You can further read about this college by visiting below

Hope it is helpful
