URGENT: Books for Paper 2 Eng Lit HL

So for Paper 2 comparative, I have been using Handmaid's Tale and Broken April as my comparative books for the past few months and I am currently considering changing Broken April to Persepolis because I have seen lots of analyses online that puts them together and none for my current combination. I have also asked Chat GPT and other AI tools which combination would be better to do and they have all said HT and Persepolis.

My problem with changing is time, since the exams is coming up super soon and I have not really read Persepolis (I've only read like half) and the fact that I compared Persepolis and Handmaid's Tale briefly in dp1 and I did quite badly (my teacher said my analyses weren't perceptive) compared to my current combo where my performance constantly oscillates between bad, average and great. I also need to now start doing in-depth analysis of the two. But I am also worried that if I don't change, I will fail because my teacher is saying my recent comparatives are not insightful and are mundane. I am just unsure of what to do now so I really need advice on which two to use.
