Till now there are no official notifications available for St. Xaviers Mumbai. This might be because most of the 10+2 results aren't released yet. So you should keep some patience and wait for the release of the official notification in the website. Its expected that the notifications will be out within 1 week prior or after the declaration of 10+2 results.
