Translate new beginner course grades to old beginner course stages?

Just curious if anyone can laydown the new course grades in relation to the old course stages. I’m going through the new beginner course now and have bought Justin’s song books which are organized based on the old format. From a quick once over it looks like Grade 1 & 2 are basically up to stage 9 but I could be way off since I don’t know everything that’s going to be in the new grade 3.



Yes grade 1 and 2 replace stages 1 to 9 but there is way more
content in the new grades 1 -2. Grade 3 is being revamped right
now and is a bridge between the beginner and intermediate
