What you need to do is identify a real problem within your school, neighborhood, town, or community. Survey friends, teachers, administration. If you can be bold, meet with public service associations or groups helping women, refugees, disadvantaged children, migrant teens… what REAL problem do they have? How can data help them solve it? Make Applied Math part of a collective toward a solution.
What language(s) do you speak beside English ? Why don’t you speak the language spoken where you live (for instance, are you at a United World College and thus come from another country than the one where thr UWC is located?)
