It's a listening breakthrough for me. I'm a fairly new learner (I've just started work on challenge 9 in level 1 of the Southern course.)
I've been listening to Radio Cymru as well, trying to have it on in the background, and I just realized I am able to understand a little of what is happening. I can now (mostly!) tell if it's someone phoning in because it's their birthday, or a poetry competition with people from different parts of Wales, or discussing the Rugby. I realized something had changed because my husband was hearing it too at the weekend and he said he couldn't pick out more than a word here or there, not enough to know what was going on.
A year or so ago when I had just done a few lessons of the old course I was at a similar level, I couldn't work out anything more than a word or two. But now I have found I can pick up a bit of context too, even if I don't yet know what they are actually saying in any more detail.
