(other times are possible if you find these difficult: see JMG).
All pupils in these forms have studied at least one play by Shakespeare, which you can use in the general question (60 minutes) about his plays. Questions will be very open, allowing you to show your knowledge of and insights into the play(s) you choose.
In addition, you can/should use knowledge of any other plays you have studied, read, or seen on stage / film.
The second question (30 minutes) will be an unseen poetry question on a sonnet by Shakespeare.
