Also, here's some good student prayers:
Prayer of Students to Mary, Seat of Wisdom
Under your patronage, dear Mother, and calling on the mystery of your Immaculate Conception, I desire to pursue my studies and my literary works: I hereby solemnly declare that I am giving myself to these studies chiefly with the following goal: that I may the better contribute to the glory of God and to the promotion of your veneration among men. I ask you, therefore, most loving Mother, who are the Seat of Wisdom, to bless my work in your loving-kindness. I also 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 from my studies, wholly to your intercession for me in God's holy presence.
Amen.
Consecration of Students to Mary, Seat of Wisdom
O Mary, Seat of Wisdom, so many persons of common intellect have made through your intercession admirable progress in their studies.
I hereby choose You as guardian and patron of my studies. I humbly ask You to obtain for me the grace of the Holy Spirit, so that from now on I could understand more quickly, retain more readily, and express myself more fluently.
May the example of my life serve to honor You and your Son, Jesus.
Amen.
Prayer Before Studying
O Lord God and Heavenly Father, bestow upon us the gift of Your Holy Spirit, that enlightened by Him, we may understand aright and may keep in mind all that we may learn, and may both begin and end all things well, to Thy glory, and in the name of Jesus Christ our Lord.
Amen.
Prayer Before Studying II
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 make eloquent the tongues of those who lack speech, direct our tongues, and pour on our lips the grace of thy blessing. Give us a diligent and obedient spirit, quickness of comprehension, 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.
Prayer After Studying
We give You thanks, merciful God, for the instruction and direction which we have received. Grant us Your grace, that we may remember the lesson and carry it into action, for Your glory and our eternal salvation. We beg You, pour forth You blessings upon our parents and superiors, our teachers and benefactors, and reward them abundantly for all the good which they have been the means of bringing to us. Through Christ our Lord.
Amen.
Prayer Asking for Light in our Studies
O King of glory, Lord of hosts, who triumphantly ascended into heaven, leave us not as orphans, but send us the Promised of the Father, the Spirit of Truth. We implore You, O Lord, that the Holy Spirit, the Counsellor Who proceeds from You, may enlighten our souls, and infuse into them all truth, as Your Son has promised. O God, Father of our Lord Jesus Christ, grant us according to the riches of Your glory, that Christ, by faith, may dwell in our hearts, and that we may acknowledge the love of Christ, surpassing all knowledge. Through the same Christ our Lord.
Amen.
Prayer to the Sacred Head of Jesus
Wisdom of the Sacred Head, guide me in all my ways.
O Love of the Sacred Heart, consume me with Thy fire.
(Say three Glory Be's in honour of the Divine Will, Memory, and Understanding.)
O Seat of Divine Wisdom, and guiding Power, which governs all the motions and love of the Sacred Heart, may all minds know Thee, all hearts love Thee, and all tongues praise Thee, now and for evermore.
Amen.
Student's Prayer, by 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.
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.
