Which is quite good for a foreigner, someone who truly learned English in his very late teens and who left for the states for a few years in his mid twenties. Needless to say that I am off the scale for non native speakers and that I would be in the top 5% if I were accounted as a native speaker. Now, before you think that I am bragging, having been in academia for a decade and a half in the US, and having my reading 80% in English for the last 25 years give me an advantage..... but of course, I prefer to stress the "non native" for my daily ego boost. Now, at a grammar test I might not do so well, as readers often point out obligingly :)
