  We describe the conductance of a normal-superconducting junction in systems
with Landau levels that preserve time reversal symmetry. Those Landau levels
have been observed in strained honeycomb lattices. The current is carried along
the edges in both the normal and superconducting regions. When the Landau
levels in the normal region are half-filled, Andreev reflection is maximal and
the conductance plateaus have a peak as a function of filling factor. The
height of those peaks is quantized at $4e^{2}/h$. The interface of the junction
has Andreev edge states, which form a coherent superposition of electrons and
holes that can carry a net valley current. We identify unique experimental
signatures for superconductivity in time reversal invariant Landau levels.
