I have now gotten to a score over 80 percent for B2. Shouldn't I be moved to B2 from B1?

Hi Judy - we're completely changing the way we handle levels shortly so this has been disabled and we leave it to you do decide which level you want to practise. You can either do C1, or go back to earlier levels to master them - whichever is going to suit your needs best. Bravo by the way!
