From the Peppi front page, you'll find a blue box that has information about your study entitlement and your student number. 

NB! This section will be available for you when your study right has been activated.

If you are a new student and you cannot open this section, it means that your study right has not yet begun. You can check your study entitlement time from the Peppi from page (as shown in the picture above). 

In the My Data section you can see the detailed information about your study entitlement and personal information.
