We live in a multicultural and multilingual environment which can offer significant opportunities. Many students speak several languages and are highly proficient. However, their full potential is often underestimated in everyday school life, as their knowledge of German is not at the required level. As a result, they end up with lower grades than they are capable of. This is exactly where porta mundi can help: with intensive, interdisciplinary German lessons which ensure that multilingualism is not seen as a shortfall but as an opportunity.
