Abstract: We present some recent results in obtaining the exact MSSM spectrum as well as reasonable interactions from compactification of heterotic string theory on Calabi-Yau manifolds endowed with vector bundles. We shall emphasize the method of attack, namely sifting through large classes of potentially viable geometries using the state of art developments in algebraic geometry and computer algebra. We will discuss how despite a seeming landscape, models with exact MSSM properties are quite rare.
