Thanks Alex.

For anyone who is still interested. I found the Syllabus and some examples of topics and themes at frenchfaster http://www.frenchfaster.com/delfb2frenchexam.htm

Thanks Alistair and Seth.

Alistair, which level did you take before? From what I've been reading the leap from B1 to B2 is quite substantial. I knew that anyway but this will be my first language exam and I want to set myself a tough challenge to pass the B2 on March 17th. I really want to be as prepared as possible as early on as possible.

Hey Alex,

There aren't any "core" topics so far as I'm aware, but you can get past papers along with the mark scheme off their website which will point you in the right direction. Having done the DELF before, there are parts which are a hoop jumping exercise, so I'd recommend coming up with some core phrases you can slip in to show off the different constructions you can use.
