Nothing is guaranteed not to turn up, but some are unlikely. Ozymandias is in the specimen paper, although that is from 2014. Bayonet charge and the theme of war is unlikely as well, as that was in last years exam. Still best to revise it anyway as it could still turn up.
what poems are guaranteed not to come up, apart from poppies and tissue?
Defo not Bayonet charge, Poppies, Storm on the island, Ozymandias or checking out me history. These have all come up on a spec or gcse paper before(2017)
