Despite being a poor scholar himself (or maybe because of it) St. Joseph of Cupertino is the patron saint of students, especially those who are taking exams. Tradition says that because of his inability to learn, the saint would study only one section of his notes and pray that it would be the only thing he was tested over–and it worked! Here are some prayers that ask St. Joseph to put a good word in for us.
St. Joseph of Cupertino, pray for us!
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.
O St. Joseph of Cupertino who by your prayer obtained from God to be asked at your examination, the only preposition you knew. Grant that I may like you succeed in the (here mention the name of Examination eg. History paper ) examination.
In return I promise to make you known and cause you to be invoked.
O St. Joseph of Cupertino pray for me
O Holy Ghost enlighten me
Our Lady of Good Studies pray for me
Sacred Head of Jesus, Seat of divine wisdom, enlighten me.
Remember to thank St. Joseph of Cupertino if you succeed in your exams!
