I'm just getting back into riding after a very long break and I was never very good in the first place. I'm booked in for a first lesson with a school that I like the sound of, but it's ABRS approved but not BHS approved. Is this something to worry about? I want to learn enough to get good enough to go hacking and generally just enjoy riding at a basic level, a bit of jumping, hacking etc, but lessons are so expensive that I want to make sure I'm getting quality instruction. TIA!
