Hi I am the pilot batch student of Christ Institute of Management, Ghaziabad. And I have been to CU Bangalore too. I found no difference between the way we have been given education and the management takes care that every facilities that a student gets in Bangalore campus is readily made available in Ghaziabad too. You can find the same teaching pattern and e-sharing of books and journals being subscribed through the university. So you need not be worried about the quality you get at any of the campuses under Christ University.
I could sense your genuine worry due to the campus being established newly but trust me my experience had been very good at Christ Institute of Management, Ghaziabad.
