excellent for beginners

So far I tried the first 5 arabic excercises and were extremely helpful . I scored 501 out of 500 ; however, I couldnt get the app to start the next set of arabic exercises . No idea whats wrong. Maybe I needed first to finish the english exercises befire gets qualified to the advanced ones .
Please help if anybody knows how.
