This is great advice coming from hawk, but he's completely correct in saying that you can't rote a Module B essayIf you say that you're doomed, then I daresay your essay isn't generic. Obviously a prepared script would adhere to as much of the rubric as possible to avoid a terrible question; but even then you must be ready for the worst. For instance in the AOS, a good way to avoid being flustered is trying to find links between certain concepts, because if you think about it, discovery is heavily interconnected, meaning you can draw threads if need be. Say if your generic essay focuses on new understandings of the individual and society but the exam question asks you to discuss the process of discovery and how it enriches the self - you talk about the voyage of discovery in which over time, your perspectives are refined which can be reaffirmed or challenged via the vicarious human experience. Then, you can slot in the new understanding bit since you come out of the process with an ontological truth that enhances the self. Not the best example, but hopefully you get what I mean.
In addition, you must have a contingency plan (extra quotes + techniques on obscure analysis) because there's a chance you need to completely discard your generic essay, just to be confident you won't get screwed over in the exam, since you do require some luck on your side. Plus knowing your texts deeply would also be of great benefit. So yeah, it's possible to memorise an essay for the AOS, Module A C, but I strongly discourage it for Module B (that's another issue to explain later).
(Soz for derailing though haha)
Module B involves a series of speeches (around 8 iirc) ranging from 1.5 - 8 pages
And from these speeches they may ask you in the question to refer to specific speeches rather than generally saying "How is this demonstrated in two of the texts (speeches in this case) you have studied"
I think this is because it's the only module that doesn't require a related (Correct me if I'm wrong)
