During your stay in Germany and at the Berlin School of Mind you must have health-insurance cover. Health insurance is a mandatory insurance in Germany.
Private liability insurance (Privathaftpflichtversicherung)
The website “How to Germany” writes: “The most important and yet the least expensive insurance cover you will need in Germany is third-party private liability insurance (Privathaftpflichtversicherung). It will provide cover to you or to any insured member of your family in the event that you commit an act for which a German court would consider you ordinarily negligent. Ordinary negligence could be a simple matter of damaging someone else’s property, for instance knocking over a vase while visiting a friend or in a shop, or causing an accident as a pedestrian by not crossing at the zebra crossing, causing bodily injury whilst engaging in sports activities.”
Third-party private liability insurance costs only around 50–60 euros per year, i.e. 4–5 euros per month. The cost of one mensa meal per month could save you literally millions of euros.
