"My son (4 Class) and daughter (6 Class) receive tutoring from Porta Mundi. We have experience with other coaching companies and none are on the level of Porta Mundi. The careful assessment by Porta Mundi of each students situation I found to be extremely thoughtful. The one on one's hone in on the children's areas for improvement and the tutors instruct in an engaging and constructive manner. We are delighted with the progress and clear improvements both children have made in Math and German respectively. I can certainly recommend Porta Mundi as the go to for individual tutoring."

"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."
