A statistics tutor for Boubacar, 12, who's falling behind

My nephew, Boubacar, is 12 and in Grade 11. Boubacar loves school but statistics has been a struggle since the school was closed during the move. The board exam is in October. 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 Boulogne-Billancourt or online, for about twelve weeks. Boubacar 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 statistics, you could change the course of Boubacar's year. Please ask me anything in the questions section. I'll answer honestly and quickly.
