Intensive course 4th grade

Because an early start makes the difference

Why careful preparation is essential for your child

The fourth grade is a crucial year for pupils, as it lays the foundation for a successful transition to the fifth grade. In Year 5, the demands in maths and German increase significantly. Experience has shown that many pupils struggle with their first major hurdle on the way to grammar school.

Through early and targeted support in the fourth grade, we ensure that your child is well prepared for the challenges ahead. Text tasks in maths and writing essays in German are common stumbling blocks that can be overcome with targeted training and preventative support.

Our courses aim to develop and strengthen the fundamental elements of these subjects at an early stage. With our specialisation course for Year 4 Primary, your child can master the transition phase with ease and without any problems.

His German level has improved significantly. He is really engaged and encouraged to learn. He has a great connection with Mrs Basler, who is very clear and patient!"

"My daughter is taking maths online with the PortaMundi Group. The online component works really well and fits in with her busy schedule. The tutor is lovely and the Porta Mundi group were very easy to communicate with in terms of what we were looking for, from classes. My daughters ability and confidence in maths has increased. It has been a very positive experience."

C. Margo, Küsnacht

"My tri-lingual son needed help in German and Franziska has been great. I was a bit sceptical if my son would stay focussed with on-line classes but he has. He even says he loves the class and that they are going well. It's clear when talking to her, that Franziska puts the child first. She is really easy to work with and is open to feedback."


N. Sandhu, Zürich

"It has been a very pleasant experience dealing with Franziska. She took her time to explain what I was asking. The extra tution definitely has help my children."


J. Wood, Erlenbach
