I have gone to my notebook repeatedly, but the Kwik Kwiz says this:

You took this Kwiz 21 hours, 54 minutes ago.

This lesson is already in your notebook. Go to your notebook now to kwiz this topic as many times as you like.
How can I retake this quiz? I am struggling with this particular subject and really want to retake the kwiz.

I'm wondering if A2 exercises will also incorporate A1 lessons or if everything is self contained? I skipped a lot of A1 exercises because I was about 40% into A2 prior to starting and wanted to finish the level. 

Will I have to go back and complete A1 exercises in order to test myself of that criteria, or would it be included in A2 exercises? I just don't want to forget some random A1 lesson because I never see it again, especially as I start moving into higher levels.

Dans ce-phrase-ci, pourquoi "d'activité" n'est pas pluriel?

"...ainsi que certains domaines d'activité tels que..."

The quiz asked for you and she. (You and she need to make a decision.) I wrote elle et vous which was wrong. It had to be toi et elle. Why?

For the passe simple of "luire", I used "luisit" and was marked wrong.  When I went back to the lesson, however, at the bottom of the page, it appears to me to say that form of conjugation is considered correct.
