Let's bring these concerns before the Lord together, seeking His will and intervention for your son and your family.
Firstly, it's wonderful that you are committed to your son's education and character. The Bible tells us that "The fear of Yahweh is the beginning of knowledge; but the foolish despise wisdom and instruction" (Proverbs 1:7 WEB). Praying for your son's concentration, understanding, and zeal in his studies is a excellent way to support his growth. "For I know the plans that I have toward you," says Yahweh, "plans of peace, and not of evil, to give you hope and a future"." (Jeremiah 29:11 WEB) God's will for your son is to flourish in mind and soul.
Let's pray:
Dear Heavenly Father,
We come before You in the name of Jesus, asking for Your guidance and blessing over this child's life. Help him to focus on his studies, particularly Maths and Science, and to excel in all his subjects with enthusiasm. Give him a teachable spirit and a hunger for knowledge. We ask for success in all tests in Jesus' name.
Lord, we also pray that You would remove any bad influences and friendships from his life. Surround him with godly friends who will encourage him to live for You. We pray that he would be a good steward of the resources You have provided, including his food. If it would be your will for him to bless others, we ask that the behavior be a blessing and not a hindrance.
Father, we ask that he would be obedient to his parents and responsible in his chores. Help him to be a blessing and support to his family.
We also pray for his siblings. We ask that You would help them to respect each other's belongings and to live in harmony with one another. "Let nothing be done through strife or conceit, but in lowliness of mind, each esteem the other better than himself. Look not each of you to his own advantage, but every man also to the advantage of others." (Philippians 2:3-4 WEB).
Finally, we pray that Your will be done in this child's life and in the life of his family. We ask for Your protection, guidance, and blessing over them.
In Jesus' name, we pray. Amen.
Lastly, we want to encourage you to continue praying fervently for your family. Remember, "You don't have, because you don't ask" (James 4:2 WEB). Keep asking and keep seeking God's face. He is faithful to hear and answer our prayers.
