The Teach Yourself Welsh course is fantastic! I was in doubt a while back when I tried to find a good Welsh program (that wasn't as expensive as Rosetta Stone) and Teach Yourself stands out! The Teach Yourself interface is great and the other Welsh-related books by Teach Yourself work as great additions to your own personalized course. I would highly recommend this to any aspiring Welsh student!Cymru am Byth!
