French help for Nhung, preparing for the school-leaving exam

My younger sister, Nhung, is 14 and in Year 10. Nhung loves school but French has been a struggle since the school was closed during the pandemic. The school-leaving exam is in March. We can't afford a private tutor, and the school's free sessions are full. We're looking for a volunteer who could spend an hour or two a week, in person in Thủ Đức or online, for about sixteen weeks. Nhung 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 French, you could change the course of Nhung's year. Whatever you can give, even just sharing this page, means a lot.
