There are no such mock test or previous year paper available online or offline so we are unable to provide that to you.

What I'd suggest you is to have a brief knowledge about the course you're opting for.for example if its bsc in psychology you need to cover 10 plus 2 level psychology subject and also science is important.

For reference you can also opt for, other universities include psychology related questions so same stands for you exam course.

For more information, you can contact Christ University itself.
