Volunteer tutor needed: chemistry for a motivated student in Grand Rapids

My nephew, Nicolás, is 14 and in Year 10. Nicolás loves school but chemistry has been a struggle since the school was closed during the pandemic. 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 an hour or two a week, in person in Grand Rapids or online, for about twenty weeks. Nicolás 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 Nicolás's year. Thank you for reading my story.
