I havent done Dickinson or Ni Chuileanain , i done Plath and Bishop but id say they will be fine! Ni Chuileanain came up last year as far as I know but I heard that the examiners said no one answered the Q about her so you shouldnt rule her out completely :P
Yes it was last years one.. I havent studied Eliot either.. I done Plath, Bishop, Yeats, Durcan & Larkin.. Yeats is a possibility due to the 1916 rising anniversary this year, and Durcan and Larkin are both due up, not sure about the others!
