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

My younger sister, Paula, is 15 and in Year 10. Paula loves school but computer science has been a struggle since the school was closed during the floods. The university entrance exam is in July. 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 Buenos Aires or online, for about sixteen weeks. Paula 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 Paula's year. Glad we found this place.
