I'm not a student, but I'm under 25, and only paying 102 CHF/month by one of the regular Swiss insurers, which I would not call half bad. My mother-in-law insists that my wife, a student at Uni Züri, keep coverage that costs something like 350 CHF/month . I repeatedly told her we should change the coverage, but my wife refused, saying that we should do what her mother suggests. Oh well.
