All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
First of all, we ask Allah to reward you for your keenness on doing good.
It is permissible for your mother and father, or one of them, to pray with you so that you get the reward of the congregation. If your mother prays with you, she should intend an optional prayer (Nawaafil) as an act of charity by praying the Thuhr again with you; the same thing applies to your father.
She should stand behind you and not next to you. For more benefit, please refer to fatwas 85798 and 86881.
If you remind your colleagues at school about the prayer and its importance and make them pray with you, if possible, then there is much goodness in this.
May Allah guide you and enable you to do good.
Allah knows best.
