Volunteer tutor needed: mathematics for a motivated student in Shubra

My son, Ghassan, is 13 and in Year 10. Ghassan loves school but mathematics has been a struggle since the school was closed during the strikes. The school-leaving exam is in November. We can't afford a private tutor, and the school's free sessions are full. We're looking for a volunteer who could spend one or two hours a week, in person in Shubra or online, for about ten weeks. Ghassan is polite, hardworking and eager. We have a quiet space and a laptop for online sessions. I'll always be at home for in-person sessions. If you're a teacher, student or professional who feels comfortable in mathematics, you could change the course of Ghassan's year. I never thought I'd be the one asking, and I'm grateful for every bit of support.
