Hi Sarah,
I don't know if this is of any use. I did a level two on course mix. It didn't have any videos so difficult to understand. However did cover early grammer structure and a few new words I hadn't learn't on this level one course. Last week however I found a level 3 which I believe was still with course mix but said it had videos and you didn't have to have any knowledge of BSL at all, but some would be useful. If you go for it please let me know what you think. I am working through a book at present then looking for a level 3 course. Happy signing
Sue
