Yeah I know that you got 14/15 for the entire section but that would mean that it should be all good if you just copy your previous answers for the final mini essay
I reckon it's fine if you do it well (top-notch standard), but markers will probably be less inclined to award you full marks for it. Just because it's playing a bit with the grey area (like when you use a 4u technique for 3u maths. Acceptable, but nonetheless slightly dodgy)
Having said this, good strategy to minimise time and maximise marks. Most students will probably do it subconsciously (i.e use past responses and then build on it.) because that's what the exam is setting you up to do.
Keep in mind though the exponential effort required for each increasing English mark. (i.e Earlier questions (2-4 marks) require only 1-2 techniques explained well, whereas a 5-6 marker is usually 6+ well explained techniques.) As such, careful not to over-achieve in the analysis for the earlier questions, but under-achieve for the analysis of the last few questions. Having excessive analysis for the first few questions (and writing excessively) will also eat into your time.
All in all, good luck : )
P.S I wish my trials were as late
