French language Q&A Forum

I would like to go back and improve A1. My score is currently 77%. How do I get it to have me review what I do not know well, which I thought was the whole point of the system.

Currently 7 of the 10 topics it gives me I have over 90%, and five of those are over 97%. These are not the topics I need to improve! I have no shortage of topics with lower scores in A1, obviously, with a 77% average in A1.

I am just clicking the "Test now" button next to A1.
