Volunteer tutor needed: computer science for a motivated student in Nha Trang

My niece, Yến, is 11 and in Form 3. Yến loves school but computer science has been a struggle since the school was closed during the strikes. The national exam is in July. 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 Nha Trang or online, for about twelve weeks. Yến 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 computer science, you could change the course of Yến's year. I hope life is good to you.
