Exercises for even harder challenges.
Just to let anybody know who doesn't already: On the main page you can click "Practice" (the blue picture of the weight/dumbbell) to test yourself using phrases and words you have already learned. I know many of you already use it but I only discovered it an hour ago and feel very foolish for not using it, it's a great tool to really improve yourself!
What do you mean with even harder challenges? I thought it just generates an exercises of your current level, not any harder?
With the exercises it just gives words from the skill tree you are on, for example masculine, but with practice mode it gives you words and phrases from everything you've done and gives you much longer sentences.
