In English, yes. In Welsh, no!
There is not an official transcript as the idea of the course is to learn aurally rather than visually. However, other learners have produced material that you might find helpful here Maintenance - SaySomethingin
Iād recommend only looking and listening simultaneously after trying the challenges without any notes first though. Try to use notes as consolidation rather than trying to learn from them - our ears are able to learn much more efficiently than we give them credit for and our eyes naturally overpower them when presented with visual material.
