the drop down box here won't let me select level 4. Anyway, in this lesson, in Write the phrase you read, several times the sentence begins with "last week", and the answer provided is "la settima scorsa". Somehow the "na" at the end of the word settimana got dropped. This happens each time the phrase continues, so to get it "right" you have to type it as settima. The same is true in the flashcards. Thanks for correcting this.
