What do the examiners mark you on? I am going to be doing my grade 7 trumpet soon, so would they mark me on tone, expression, things like that? Thanks

'These music exams', written by chief examiner Clara Taylor, contains all the information you need about how you are marked etc. It also contains much other useful information. Here is a link to the guide as a pdf file: http://www.abrsm.org/resources/TMERevised05.pdf

Hope this is helpful!!
