A computer science tutor for Mizanur, 15, who's falling behind

My son, Mizanur, is 15 and in Year 10. Mizanur loves school but computer science has been a struggle since the school was closed during the floods. The school-leaving exam is in September. 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 Rajshahi or online, for about sixteen weeks. Mizanur 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 Mizanur's year. Please ask me anything in the questions section. I'll answer honestly and quickly.
