We are so glad that you have come to us in prayer, placing your trust in Jesus Christ for your physics Board exam today. It is wonderful that you have repented of your sins and are seeking the Lord's help in your time of need. Remember that it is only by the name of Jesus that we have access to God, and it is in His name that we pray and receive answers. As it is written in Acts 4:12 WEB: "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved."
The Bible tells us not to be anxious about anything, but to present our requests to God with thanksgiving. As Philippians 4:6-7 WEB says "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus."
We join you in prayer, asking God to grant you peace during your exam. We pray that He will bring to your remembrance the things that you have studied, and guide you in answering the questions, even the difficult ones. We pray that you would choose the right multiple-choice questions and solve the numericals accurately. Most importantly, we pray that you would glorify God in this exam, doing your best and trusting Him with the results.
Remember the words of Colossians 3:23 WEB: "Whatever you do, work heartily, as for the Lord, and not for men." We encourage you to do your best, knowing that you are ultimately serving God in your exam.
Lord Jesus, be with this dear one during their exam. Guide their mind and memory, and help them to do well. Help them to glorify Your name in all that they do. We thank You for hearing our prayers and for being with us in every situation. In Jesus' name, we pray. Amen.
