My cousin is from this institute, so I think I am eligible to answer your question.
It is a well-established institution with a well-qualified faculty and a placement track record ranging from 60% to 90%. According to the recent placement highlights the average CTC offered at the institute is 17 LPA.
The university has all modern conveniences, such as air-conditioned classrooms/laboratories, a fine canteen, and a pleasant environment.
However, you have to look out for expenses as if you know it is an expensive university with fewer than 210 days of classes every year. So if you can afford it, then you should definitely go for it.
It really will not matter as the faculties of B.Sc. IT and BCA are more or less the same. They are taught similar subjects.
The only difference is that in B.Sc. IT is majorly concerned with the research aspect of the computer, while BCA is concerned more with the application of computer science. But both are equally great courses with proper scope for the future.
Amity Lucknow offers great facilities, infrastructure and highly supportive and experienced faculty members for all the courses. Go for the one you are interested in and want to make a career in.
