A chemistry tutor for Liang, 12, who's falling behind

My nephew, Liang, is 12 and in Year 10. Liang loves school but chemistry has been a struggle since the school was closed during the floods. The university entrance 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 Riverside or online, for about twelve weeks. Liang 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 chemistry, you could change the course of Liang's year. You're what makes this possible, and I'll never forget it.
