Why read the book you're meant to be writing about when you can skip to reading criticisms about the book you know nothing about to get started on your essay faster? #SoProductiveBetween Sparknotes, all her tutor's emails and notes, and all of the arguments and counterpoints from her seminars and Blakeney's Notion, she has the rigid skeleton of an essay with a thesis that she knows the person grading it will agree with, counterarguments provided by other students and a tonne of critical material because that's what she spent most of her time on.
All she has to do is put it all in her own words (and run it through a spellchecker and have Blakeney/a tutor proofread it to undo all her misspellings and malapropisms) and she has an essay that'll get a high grade with little effort and it's perfectly within the rules.
That might work great for the first two years where you're given strict, prewritten essay titles to choose from, but in a dissertation she now has none of the academic skills or ability required to function, and can't borrow ideas from other people, so it's no shock that she's floundering and hates uni now.
During my first year, a girl in my cohort used to do her essays by writing down everything she thought was correct about the topic, then reading around to find references that backed up her ideas. She never did any reading beforehand. She averaged 65 in first year, but then plummeted to 48 average in second year so she stopped doing assessments like that. It's a strategy that works for a while, but can't carry you through a whole degree - especially not a dissertation.
