From N=2 supersymmetric classical to quantum mechanics and back: the   SUSY WKB approximation
  Links between supersymmetric classical and quantum mechanics are explored. Diagrammatic representations for \hbar-expansions of norms of ground states are provided. The WKB spectra of supersymmetric non harmonic oscillators are found.
