QMED COURSE or just test

i have 166 12 hour days of sea (as a wiper) which i believe is really 249 days for the coast gaurd i believe. now my question is. are there any schools where i could get my qmed rating that isnt a 30 day course or longer. when im home id only like to use no more than 14 days to take a course and just get the lisence. Or i could test for it at the coast gaurd station but then id have to apply, then get approved, then finally take the test. im looking for whatever is the fastest route to finally get this done.
