Even if it is only once a year, I suggest you follow the steps of 4, 6, 8, 9, 10 or 4, 6, 8, 10.
Four levels of regular script, six levels of official script, eight levels of regular script or official script+running script * nine levels are the same as *. 10 level block letters or official script+running script+cursive script.
I am the former, and some students don't have time to take the latter. You can consider it according to your own situation!
PS: The requirements of Grade 9 are higher than Grade 8.
