Hello
Hope you are doing well,
A lot of colleges and universities have changed the duration of the course as based on the new education policy, however christ University is a deemed University and is not necessary that they will follow this change, no offical announcement has been done by the officials of the University as of now and the course is still a three year degree for the timing. For better information you can call the university and ask them if they are going to change it as of now or not.
Thank you
