If my student got the wrong key in the transposition question would they lose all the marks? What about in the transposing instruments question?

CNCM awards part marks in the junior grades if the candidate wrote in the wrong key, but transposed the notes correctly, or if they wrote in A major and the key should have been A flat major. However, when transposing to or from concert pitch, the key is crucial, and partial marks are not awarded in the higher grades.
