The Directions lessons are pretty mangled.
I just did a strengthening exercise for the Directions lessons and I thought I'd never get out of there. The links between the recordings and the slides are so screwed up that it is often wrong to write what is being said. I probably made 10 mistakes through the exercise and every one of them was because of a misalignment between the recordings and the slide they were linked to.
And then the general interface glitch that others have also reported about kicked in and I would get slides with instructions to "write was is being said" but the recording never played, and if I put in an answer, it would give the sound of an incorrect one, but show at the bottom of the screen that it was correct.

At any rate, I hope I don't have to do that lesson again any time soon.
Don't worry, if you made that many mistakes you'll have to strengthen it again within three days. Hahah
I just re-did the whole level using the desktop version in order to report all the errors I encountered while strengthening it in the app. But I didn't encounter any. Are things fixed in the desktop version that aren't in the app?
