a short and intensive course of study
短期集中学習コース (tanki shuchu gakushu kosu)
"I had to take a crash course in programming before starting the job."
"仕事を始める前に、プログラミングのクラッシュコースを受けなければなりませんでした。" (shigoto o hajimeru mae ni, puroguramingu no crash course o ukenakereba narimasen deshita)
to try your best or use all your energy
to go beyond the usual limits; to innovate boldly
to make a wrong assumption
to bear the burden of an important duty or obligation
an unusually large harvest
a discovery that changes understanding in a field
