I have spoken to another teacher who thinks that the piano is not a valid reason to not start preparation or do the exam.
But teacher wont even start preparing me for AMus until I have a Kawai piano (right now I have a Victor Baby grand and a upright concord) - because apparently it would be a waste of time and i might get bad habits if i started preparation on this PSO.
But even before he heard me play - he knew what grade i was and that I had a scholarship - he asked us to buy a new grand...
