  The paper studies the rate of convergence of the weak Euler approximation for
solutions to possibly completely degenerate SDEs driven by Levy processes, with
Hoelder-continuous coefficients. It investigates the dependence of the rate on
the regularity of coefficients and driving processes. In addition, the rate
robustness to the approximation of the increments of the driving process is
studied and approximate Euler scheme considered. A rate of convergence is
derived for an approximate jump-adapted scheme as well.
