Right. My 10-yr-old son has a Grade 4 exam looking horribly imminent (end of this month). He's keen and generally does pretty well on his pieces but barely scrapes through the scales and sightreading.
He seems to have a LOT of scales to practise this time round.
I don't always 'hear' when he's getting them wrong especially minor scales. DH (who is musical but generally gets home too late to listen) heard him yesterday and said, 'Oh god, he's miles away from knowing these scales properly.' So any tips for making best use of practice time? He'll have three more lessons before the exam.
