Dear Candidate

Practice for Entrance Examination can be done by 

Solving previous year papers and

Giving mock tests.

Many university do not disclose their Entrance Examination papers. The ground reality is that if such university authorities decides not to disclose previous year papers, it is most likely that you will not find it anywhere in the internet. So I would suggest you to dig the official website for the same. You can also refer to various third party sources on the internet like shiksha,allindiajobs etc for mock tests.

All the best
