I have practised the lesson 5 or so times, each time it has been 5-6 rounds of "Die Bücher haben wenige Rezepte".

As in, multiple choice, listening, translating the same sentence. Over and over.

2 or so rounds will be "Die Untersuchung dauert wenige Minuten" or "Im Haus gibt es wenige Schwestern." or other sentence where I haven't learned most of the words or structures.

It also seems to decay much quicker than any other lessons.

Is there some way to fix it, or mark that I never ever want to repeat the lesson again?
