And I went through GCSE, where I studied Macbeth, without ever seeing the play performed once. Just the odd video, and not even the McKellen/Dench one! In fact, this production will be my first ever Macbeth, a good 5 years late.
These days with controlled assessments you might only read two scenes of the play, believe it or not. A friend of mine was told on no account to show them the whole play - just concentrate on the scenes relevant to the question asked in the assessment, which, of course, the pupils know and prepare in advance.
