According to the link given, there are 12 golden owls in Arabic already!
There were a few posts of people who speak Arabic trying it out to see how this is like, so some may have took the test and skipped through a bunch of this and finished early. Also, some comments were all in Arabic, so they may have finished early too.
I agree, in my line of flags you see the flags for the Dutch & English courses. I've got owls for both of them. Just tested & tested out until i got those nice owls.(with flags, ja!) Made it in under a week & unlike this short beta course, the Dutch one is a bit longer.
As a Dutchy this was not because i needed to learn those languages, but i wanted to see what the course was like so i'd better be able to help other learners with their questions. The English to Dutch course is really good & funny. (^.^)
