This paper is devoted to the problem of the WKB method inaccuracy. By comparing the WKB with a reference finite-element numerical method we show the magnitude of the WKB solution error. Moreover, we show in the paper what kind of simplifications made in the WKB analytical approximation led to its inaccuracy.
