An accounting tutor for Sabina, 13, who's falling behind

My younger sister, Sabina, is 13 and in Form 3. Sabina loves school but accounting has been a struggle since the school was closed during the floods. The national exam is in April. 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 Dhaka or online, for about sixteen weeks. Sabina 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 Sabina's year. Even a small gift gets used right away and I'll thank you myself.
