Aspects of Supersymmetry at LEP II
  We give a short introduction to the concept of low energy supersymmetric models and their phenomenological predictions. In view of the future LEP II results we have to parametrize these predictions in a model independent way without too many simplifying assumptions. The study must therefore include models with {\it non--universal} soft supersymmetry breaking terms. We show that such non--universalities might have significant influence on the properties of these models.
