  This paper provides an overview to three recent papers on the bottom up
approach to GUTs in F-theory. We assume only a minimal familiarity with string
theory and phenomenology. After explaining the potential for predictive string
phenomenology within this framework, we introduce the ingredients of F-theory
GUTs, and show how these models naturally address various puzzles in
four-dimensional GUT models. We next describe how supersymmetry is broken, and
show that in a broad class of models, solving the mu/B mu problem requires a
specific scale of supersymmetry breaking consistent with a particular
deformation of the gauge mediation scenario. This rigid structure enables us to
reliably extract predictions for the sparticle spectrum of the MSSM. A brief
sketch of expected LHC signals, as well as ways to falsify this class of models
is also included.
