I know there are several threads about this but they're out of date... so I thought I'd ask for updated opinions!
DS would be doing Trinity for his Grade 8 piano to avoid having to wait for Abrsm's new syllabus this summer. He has done Abrsm all the way till now but Abrsm allows for so little overlap they're giving us little option.
Still discussing with teacher.
Anyone thinks of any reason NOT to do this?
