Don't take this college at all! I am a native of lucknow this college is in ruins.The permanent campus has not proper classrooms ,hostels are unbuilt classes have sand bags kept inside it looks like a completely unbuilt building even  iiit allahabad is not here to provide help in placements try for a better college,from next year there is going to be a huge downfall in placements as lucknow is not a very popular place for IT companies and the fees of this college is enormous.

But i have reservation of general ews 

Well Ews system has only been implemented this year, so there are no previous year statistics on how it would affect your admission chances.
Hope you understand.
