I write all the sight-reading exercises I use when I'm rehearsing with exam candidates so that there's never any chance of duplicating whatever their teachers use. My examples are closely based on the syllabus but it would be very helpful to have more information about the length of the Board's published examples and the time signatures used. If you have a copy of any of the books and would be willing to give me that sort of general info I would be very grateful. Please let me know if I may PM or email you. Just off to rehearse with two G2 cornet candidates.
