About the Strumming SOS category

Master the art of strumming and become a confident rhythm guitar player! Full course here.

Advice please.
I was wondering about these courses and how much benefit I would get from grade 1 as opposed to going straight to grade 2.
I still class myself as a, “learning to play”, guitarist rather than a, “I play guitar”, guitarist, but, with my strumming, when attempting to play through songs or part of songs, I have got to a stage of not being, “rigid”, with my strumming, and without thinking are throwing in, “extra” strums or “fills”, that just “feel” right, almost on auto-pilot.
I don’t want to miss out on important teaching by missing a grade, but, don’t want to purchase something that may not be fully appropriate for me.
Any help would be greatly appreciated.
Kind regards
