We met Katja over 2 years ago when my son, Matthew, needed help with conversational German during his GSCE years. He worked with Katja on a weekly basis for four terms in two blocks working on all areas of the curriculum but particularly, speaking and listening. Matthew says, "If it hadn't been for Katja I wouldn't have got an A!"
Matthew enjoyed his sessions with Katja and she was particularly kind and supportive to us both as Matthew's father died suddenly at the end of Year 10.
We had a good working relationship. Katja was approachable and able to be flexible over days and times to suit Matthew's commitments over the two years.
I would highly recommend Katja.
