If you’ve made lots of progress with your Welsh and you’re keen to be using it in the workplace, there is a course coming up in Aberystwyth that might interest you. It’s called Cymraeg Proffesiynol and will be held over a week in August. There is a choice of dates - 15-19 or 22-26 - and you can stay in the Student accommodation or just attend as a day student.
I can’t upload the file with all the information here as it’s too big apparently, so if anyone would like it just PM me your email address and I’ll send it to you.
