For some reason I got it in my head that the cut off point for JLPT applications was mid-October. It wasn't. It was yesterday.
But no fear - this isn't a recent discovery - just one that I made last weekend.
I duly got the application away recorded delivery on Monday with, hopefully, enough of a margin to get it in by Friday, 6pm. But then you can never be sure with the terminal patient, the Post Office. And sure enough I may have been scuppered by the strike that has brought the entire postal network to a grinding halt mid-week.
So now I have just to wait...
