I have now been studying Portuguese for over 2 years (6 months of DuoLingo, which was surprisingly good, followed by 20 months of tutoring). My teacher says she thinks I'm at B1 (which is kind, but almost certainly untrue).
My reason for originally studying the language appears to have evaporated. Or at least, to have lost urgency (obrigadinho, Lei da Nacionalidade), so I'm left with the question of whether to switch to something else.
