Are Passages/Poems Repeated?

[whodis]

How likely are passages/poems that featured in previous years' exams to appear in this year's exam? Just so I know whether I need to study them as intensely as those that haven't

They have been, especially for poems, been repeated in the past.
This is especially likely when there are only three unexamined poems left; while they could give you those three, they could also use just one of the unexamined ones.
However, it is unlikely they will use the exact same passage from the same poem, especially if the poem is longer and has multiple possible passages.
