I've never tried out an exam centre piano before the exam, and I don't think it was an option at my centre - a local music teacher's music room on a baby Bechstein. Instead, I tried out every other piano I cound find, and still use that technique now. If I can play my pieces on my piano, my teacher's piano, a really clapped out piano, a digital piano etc. then whatever the exam piano, it's unlikely to phase me too much.
I've done that!
I'd just like to describe something relevant that happened at a local festival recently; maybe it's common, but I've never experienced it before. As each entrant went up to play, the adjudicator actually told them to try out the piano. Some seemed grateful for the opportunity, but most seemed to be doing it only because it was expected, and clearly felt ill at ease to do so in front of an audience. They had no idea what to actually DO to "try out" a piano, and most ended up giving a preview of their first competition piece. We all knew, therefore, before they had even started, who was in the running and who was not. Obviously an exam scenario is different, but it would be useful for all candidates to have a rehearsed idea of what to actually DO if given this opportunity - or if they intend to ask for it.
