Ineffable Creator, Who out of the treasures of Thy wisdom has appointed three hierarchies of Angels and set them in admirable order high above the heavens and hast disposed the divers portions of the universe in such marvellous array, Thou Who art called the True Source of Light and supereminent Principle of Wisdom, be pleased to cast a beam of Thy radiance upon the darkness of my mind and dispel from me the double darkness of sin and ignorance in which I have been born.Thou Who makest eloquent the tongues of little children, fashion my words and pour upon my lips the grace of Thy benediction. Grant me penetration to understand, capacity to retain, method and facility in study, subtlety in interpretation and abundant grace of expression.Order the beginning, direct the progress and perfect the achievement of my work, Thou Who art true God and true Man and livest and reignest for ever and ever. Amen.
Another from St. Thomas Aquinas - patron of students. We used this one in Grad. school frequently.
Grant, O merciful God, that I mayardently desire,prudently examine,truthfully acknowledge,and perfectly accomplishwhat is pleasing to You,for the praise and glory of Your Name. Amen.
A good prayer to use before studying.
A Prayer before studying for exams.“God of Wisdom, I thank you for the knowledge gained and the learning experiences of the semester. I come to you this day and ask you to illuminate my mind and heart. Let your Spirit be with me as I prepare for exams, guiding my studies, and giving me insight so that I can perform to the best of my ability. Please grant me the strength to handle the pressure during these final days of the semester, the confidence to feel secure in my knowledge, and the ability to keep an appropriate perspective through it all. Help me to keep in mind what is truly important, even as I focus my time and energy on these tests in the immediate future. Finally, may I sense your peace in knowing that I applied myself to the challenges of this day.”-Amen-
Here is a nine-day novena (in pdf format) for those who want to start today and end next Wed, the end of finals.
Two prayers from Catholic.org:
Under thy patronage, dear Mother, and calling on the mystery of thine Immaculate Conception, I desire to pursue my studies and my literary labors: I hereby solemnly declare that I am giving myself to these studies chiefly to the following end: that I may the better contribute to the glory of God and to the promotion of thy veneration among men. I pray thee, therefore, most loving Mother, who art the Seat of Wisdom, to bless my labors in thy loving-kindness. Moreover I promise with true affection and a willing spirit, as it is right that I should do, to ascribe all the good that shall come to me therefrom, wholly to thine intercession for me in God's holy presence. Amen.
Incomprehensible Creator, the true Fountain of light and only Author of all knowledge: deign, we beseech Thee, to enlighten our understanding, and to remove from us all darkness of sin and ignorance. Thou, who makest eloquent the tongues of those who lack utterance, direct our tongues, and pour on our lips the grace of thy blessing. Give us a diligent and obedient spirit, quickness of apprehension, capacity of retaining, and the powerful assistance of Thy holy grace; that what we hear or learn we may apply to Thy honor and the eternal salvation of our own souls. Amen.
Lastly, a prayer recommended last time I posted prayers for finals:
