Good luck on your finals everyone. Here is a prayer to St. Joseph of Cupertino, the patron saint of students.
O Great St. Joseph of Cupertino who while on earth did obtain from God the grace to be asked at your examination only the questions you knew, obtain for me a like favour in the examinations for which I am now preparing. In return I promise to make you known and cause you to be invoked.
Through Christ our Lord.
St. Joseph of Cupertino, Pray for us.
