Hi there. In response to your query the answer would depend on the type of University you are going to aim at and the subsequent examination for the same you have to appear for. Most universities nowadays are linked to a central examination authority, similar to NTA. Hence you would have to look upto those websites for information. Some institutes however do possess the their own respective entrance examination mostly privatised institutions, so for that the information is available on their website.

Hope this answer helps; best wishes
