Hi Astha,
To practice online mock test you can join T.I.M.E.S mock test series once you're done with your preparation.
It's the best for preparing and practicing mock test and would give you the same difficulty pattern of paper like real CAT,XAT,IIFT,CMAT, MAT,MAH CET,NMAT,SNAP,IBSAT.
Wish you all the best.
