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.
