  The peculiarities in tunneling characteristics have been studied in the light
of the controversy between s-wave and d-wave character of High $T_c$
superconductivity. We show that anisotropic s-wave gap has the same low voltage
power law conductance and two peak structure in the density of states as d-wave
superconductors. The asymmetric tunneling conductance and zero bias conductance
for the c-axis tunneling is shown to occur because of finite band splitting
coming from the interlayer hopping parameter.
