Web services

lulang guo,

By default moodle doesn't have such web service available to fetch quiz questions and answers,So you need create your own local plugin and implement web service there. ( * plugin are written using php scripting and i don't have much idea on php script  )

Please find the below links  which may be helpful for you.
