    Re: "efficacy" "efficiency"

    put it this way:

    You studied English.
    Then you must prove you are able to study abroad.

    IF you can pronounce words correctly - that's efficiency - but it does not mean you can talk to people fluently.

    IF you have problems pronoucing a few words but people can understand you easily - that's efficacy - you achieved the goal - you speak English.

    Perhaps you can do both.

    Tell me, what is the efficacy of this herbal remedy >> How good will this remedy be in treating a medical condition.

    The efficiency of the train service is the success of the operators >> It works, and works well.

    Re: "efficacy" "efficiency"

    I think of efficacy as an absolute power, efficiency as a relative one, whether it's relative to input energy (up to 100% efficiency) or relative to an outside standard (as in rail, compared to Japan Rail or the SNCF).
