goodbyestranger most of the issue is that the war cohort got prompted to study the question before the exam, a suggestion which many the majority of?) schools took up. However, a second issue is that the love cohort got stuffed with Singh Song. If. The exam board was out to make things easy, they'd have gone with When We Two Parted, or similar, but no, they went for one of the least popular poems.
All DC were supposed to study all poems, but the nature of it is that there isn't time with lots of other exams going on to study them all in depth. So the students are advised to do half in depth and half more superficially. I am willing to bet that Singh Song was in the superficial group for most of the love cohort.
That's the luck of the draw, but it seems unfair to give one half a poem they are unlikely to have chosen to study in depth whilst giving the other cohort a poem that they were encouraged to study in depth.
