Volunteer tutor needed: accounting for a motivated student in Cardiff

My younger brother, Aaron, is 12 and in the final year of school. Aaron loves school but accounting has been a struggle since the school was closed during the pandemic. The GCSE 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 Cardiff or online, for about ten weeks. Aaron 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 accounting, you could change the course of Aaron's year. Thank you for reading my story.
