Because learning opens doors

The sports holidays are the perfect time to study intensively and prepare specifically for the Gymi exam. Our intensive week focuses on the core subjects of maths and German so that your child can review the most important topics and eliminate any uncertainties. With porta mundi's learning strategy approach, learning is not only efficient, but also sustainable, so that your child can be perfectly prepared for the upcoming Gymi exam.

Why our practice courses are sustainable and crucial

Focused repetition: Our intensive courses are designed to repeat the key topics in maths and German. This helps students gain confidence and consolidate their knowledge.

Competent teachers:
Our experienced teachers specialise in preparing students optimally for the Gymi exam. They are happy to share valuable tips and methods that are guaranteed to help your child master the two exam disciplines with confidence.

Individual support:
With a maximum number of 5 students per course, we offer personalised and intensive support. This means that your child receives exactly the support they need to maximise their abilities.

Flexibility and convenience:
Our courses take place both on site in Erlenbach and online via Zoom. This flexibility allows you to choose the form of participation that best suits your situation.

Sustainable learning:
Through targeted repetition and practical exercises, we promote a deep understanding of the learning content, which ensures your child's long-term learning success.

Taking part in our practice courses during the sports holidays is a valuable opportunity to deepen your child's knowledge and prepare them for the Gymi exam in the best possible way. Use this opportunity to give your child a decisive advantage.
