I didn't tick boxes for those words which I recognized and which I would not stop and pause for when encountering them in context, but which I couldn't really define. I did tick the boxes if I could more or less define them, though only vaguely. So I dare say if I'd done it the same way as Camilla I'd have scored a good bit less than her, as well I might...

The non-native speakers get a rather extensive questionnaire about how they learned English, but I dare say they should've given a bit more range on their answering options than just "lots", "somewhat" and "not much". I've spent most days during the past ten years of my life reading/writing English one way or another for at least one hour a day and often more, what with this and other websites and the people I met here - and I'm not sure if they entirely realize how English-language music and movies have near-monopolies in a place like Flanders, either. It probably would've been more accurate to answer "absurdly much" to questions about how much English I practiced outside formal classes.
