I've been looking at the content of the ABRSM theory grade syllabus. It looks like with minimal work I could know all the Grade 5 content (you can skip grades up to G5 but beyond that you must have G5 before you can sit 6 or above).
But I have no idea what a theory exam is like - is it like sitting a written test or is there still music involved? For instance could someone who knows theory inside out but is tone-deaf (or actually deaf) pass just as easily or does it test your aural skills (musical ear) too?
Can people who have actually taken theory tests of medium-higher grades with ABRSM or other recognised exam boards (please state which) describe what the exam process was like for the grades you have taken?
