The International Ski Club Zurich (ISCZ) ski school finishes next weekend, although there is talk of further courses in March, but that is not confirmed. I've no idea at what levels they will be, but the gist of the conversation was follow on courses. I'm a member of the club and on this course (total novice) I can say our instructor is great, his name is Joshua and works for
