So....today's collocation is "to put your money where your mouth is:" to support what you say by doing something practical; to show by your actions that you really mean something.
I just picked up the DELE Superior C2 book at FNAC. I'm not surprised that I don't know a lot of the vocabulary in it, but I'm very happy that I have six or seven months to prepare for the exam.
The big day comes at the beginning of November. After all the hell I put you guys through, now is your chance to laugh at me. :)
