I am focusing on Twelve Angry Men for the exam and I think Juror 4 is the strongest. He is the only one that remains emotionally uninvolved, almost unhuman. He doesn't sweat like the others until his memory is proved to be fallible - a human trait.
My essays for Twelve Angry Men always follow the same structure, each paragraph is based around a separate juror or a couple of jurors. As a play is driven by the characters, the themes are embodied by the characters and i have had huge trouble structuring my essays any other way.
From what I've studied and been told, there are only two possibilities for the question to fall under - and there IS overlap in these:
1. Characterisation Themes (usually argumentative)
eg; which character is more important, the jurors have more significance than the boy on trial, the most significant vote
2. Rose's views, values, and intended Themes (usually discussion)
eg; prejudice and bigotry, personal grievances clouding truth, justice, societal flaws
However, it could also be a blend, as things are rarely 'simple'. Something more like:
"The jurors in Twelve Angry Men conclude that justice is truly unattainable",
however, it could be completely different. We just need to know the text enough to pick up anything and support it.
Pre-preparing essays might help, but will probably just skew our responses.
Prep essays are more for comfort with writing time and ability to respond to a topic, not so much word for word revision.
The question will most likely not directly ask about authorial choices, for example
'WHY DID ROSE WRITE A PLAY AND NOT A PICTURE BOOK?'
but more like
'Twelve Angry Men says more with the stage direction and character physicality than with the dialogue. Discuss'
Everyone should mostly have a different writing style and interpretation of the text at this point, and the beauty with English is that it's pretty much malleable, as long as we support our contentions. Responding to the topic is what we need to do.
This is not a chance to be obscure and experimental, we need solid writing and evidence to get good marks.
We should always mention that it is a play, that the characters (and what they say) are constructs that Rose has built to talk to the audience, no matter what the topic is. Also the historical context, but we can't let that distract us from the 'meat' of the text - like all things, add more depending how relevant it is.
IN SHORT:
If the question asks which Juror is strongest, you SAY which juror is strongest.
And then you say why.
