My IELTS student is going to study Hotel Management at a college in Bern. He wants to learn German, and I told him that I can teach him the basics, since I studied basic German at university. But I looked up Wikipedia and found out that Swiss German, especially Bernese German, is quite different from standard German! Would he be able to get by in Bern if he spoke standard German? Would it be worth learning it?
Would it also be a good idea for him to learn French? I can teach basic French as well.
