Hi Aryan,

To practice mock test I would suggest you to join T.I.M.E.S mock test. T.I.M.E.S is the best coaching institute for providing the mock tests and for management entrance exam. 

In their mock test series they itself provide you with the previous years exam papers for all the entrance exams like CAT,IIFT,NMAT,NMAT,IBSAT,XAT,SNAO,ATMA,MAT with their solutions.

This will help you to practice various other mock tests as well that are prepared on these exams patterns as well.

wish you good look.
