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.
