Studying opens up many opportunities, but it also involves costs: as well as course materials and books, you’ll need money for living expenses, accommodation or a termly travel pass. However, there are various ways in which you can fund your studies. Regardless of your financial situation or that of your parents, this gives you the opportunity to study.
Every school leaver should have the opportunity to pursue a higher education course that matches their interests, even if their parents’ financial support is insufficient to cover the costs. That is what BAföG is for.
