A Prayer Before Studying For An Exam

Dear Lord Jesus, I pray that as I settle down to do my studies today that You would help me to collect the thoughts of my mind so that I may become really focussed on my work and complete all that needs to be covered today.
Give me a focussed mind, help me to make the best use of the time today and keep me from the many distractions that too often divert my attention away from this important study.
Lord, You know that I have an exam coming up in the not to distant future and I pray that You would give me the grace to learn my studies, and to retain what I have learned. Give me an understanding mind and help me to concentrate so that I may retain and apply the knowledge that I am gaining. Thank You, Lord. In Jesus' name I pray,
