For many, the decision about what and where they study, will be amongst the biggest they will ever make. And even before that, in fact while still at school, vital decisions will be taken. So I imagine the ideal University is one which also offers teachers, students and parents concrete help in things like, learning techniques, presentation training, individual performance analysis, application training, media workshops, didactic discussions, orientation help and student counselling services. All of which are offered by the Karlshochschule.
These take the form of workshops, lectures, "taster courses" and personal talks, either at the schools or at the Karlshochschule and are usually free of charge. These offers are focussed on either school students, parents, or teachers, or on all three groups together. I imagine the best for me would be to look at what is most important to me and click one of the info boxes.
