O humble St Joseph of Cupertino, singularly favoured by God in the difficulties of study and the worries of examinations, implore the Holy Spirit to enlighten my mind and aid my memory in the search of His truth and wisdom.
Help me especially in the decisive moments of examination, protecting me from that forgetfulness and disturbing anxiety which often accompany them, so that I may grow in knowledge, love and service of God from whom flows that wisdom which leads to eternal life.
Amen

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 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.
Amen.

St. Thomas Aquinas

Creator of all things,
true source of light and wisdom,
origin of all being,
graciously let a ray of your light penetrate
the darkness of my understanding.
Take from me the double darkness
in which I have been born,
an obscurity of sin and ignorance.
Give me a keen understanding,
a retentive memory, and
the ability to grasp things
correctly and fundamentally.
Grant me the talent
of being exact in my explanations
and the ability to express myself
with thoroughness and charm.
Point out the beginning,
direct the progress,
and help in the completion.
I ask this through Christ our Lord.
Amen.
