One of the most beautiful collections ever uploaded, if only to inspire you to receive, analyse and use words in a more compelling or thoughtful way and marvel at their ability to conjure untested emotions and fresh images that aim to draw you into a writer's intentions.

I wouldn't blame you given the past and present struggles to master Paper 2 given the types of language you are exposed to in other subjects where tone, nuance and sound are all taken for granted in favour of one-dimensional remarks that point to some equation, chemical reaction or organism in plain and flat terms. I hope I am wrong but a careless student may allow it to seep into GP and miss every turn or corner that aims to sift out the more sensitive and careful readers/ writers from those who only see a wall of words on a page. Critical distancing is an important skill here.
And yes, you should go again and spam only for econs...something even your tutors will advise against. Good writing defines you as a good writer and will always be applicable in all disciplines beyond Literature, Linguistics and the English Language.
Once again, there is more to life than just mugging and passing exams.
I hope the excerpts here will ignite your mind and heart and enrich the skills you have already acquired especially in the use of English, an area to score in both papers to come.
