Ok, me being Catholic and all (and by that I mean that I also pray to saints), I've been praying for a lot of people lately, especially those with finals. So I've decided to post the prayer I use.

O Glorious St. Anthony, divinely endowed with the learning of the saints, I desire to place my studies under your protection, guided by your example, I wish to draw all my knowledge from the Sacred Hearts of Jesus and Mary, with your assistance, I will study to do my duty, in a spirit of penance, and with a pure intention. May the "Father of Lights" grant me through your intercession and bright intellect, a sound judgment and retentive memory. Help me to study patiently, orderly and constantly to develop in me the gifts of God and always to make good use of them according to His divine will. O dear St. Anthony, grant me to succeed in all my studies and examinations if it be for the greater glory of God and the benefit of my soul. Amen

Good luck everyone!
