When comparing two poems in the exam question in GCSE for english, can you compare it by saying they're both similar? Or do you have to compare 2 poems that are different to each other?
As long as you can come up with a number of points and expand on them, you're welcome to pick either way! Sometimes it's good to pick two that have similarities but also differences so you can evaluate more and have more points to discuss
I would always compare it to another similar poem as it is very easy to spout on for two pages how two poems have nothing in common and will not get you high marks. It takes a lot more thought and engagement (and revision time) to talk about how two poems are similar, and will thus get you the top grade boundaries.
