[Plugin: WP Survey And Quiz Tool] Change or translate Score Format

Hi everyone

I would like to change the Format of %SCORE%

The actual format is : “votre score : 8 correct out of 15”

And I Would like to display ” votre score : 8/15″

or i would like to translate (in french) “correct out of” to “correcte(s) sur” (I can’t find it in the php files…)

Thanks for your help !
