Free tutoring hours for Khang: accounting online or in Cầu Giấy

My younger brother, Khang, is 14 and in Year 10. Khang loves school but accounting has been a struggle since the school was closed during the pandemic. The school-leaving exam is in February. 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 Cầu Giấy or online, for about sixteen weeks. Khang 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 Khang's year. I never thought I'd be the one asking, and I'm grateful for every bit of support.
