I disagree if I'm honest. I think she'll apply to Oxford and actually be successful this time round.
You need a strong academic showing at undergrad, which she has; Oxford requires a first-class or a strong 2:1 and she has a strong first from a very good RG university. With some modules at 80 and I don't think a single one being below a 74, that definitely satisfies that requirement. There is also no interview for postgrad English at Oxford. If there was, I wouldn't be surprised at all if she failed to get in, as interviewers will quickly realise she isn't as smart as her grades perhaps indicate.
While I think she'll get in, I certainly don't think it'll be the right choice for her and Oxford will swallow her alive. Doing a Masters in general is difficult with the additional pressure of doing much more individualised study, but to do it at an intense environment like Oxford will be far too much for her. She'll stick at it as it's "been her dream", but I expect a train wreck.
Ultimately, she'll want to go to Oxford to try and vindicate her previous rejection and prove the nasty bullies who didn't let her in the first time round, while giving up some spiel to not give up on your dreams and it being destiny/fate or whatever. You can add in the extra bonus of being able to put "Oxford" in every single video title, whether that's "7am Morning Routine for an Oxford Student" or "How I Manage to be Productive as an Oxford Student".
All in all, it's to do with what other people think, which she cares far too much about. She should really get out of the safety net of education and into the real world. Ah well, at least it'll provide us with entertainment.
She'll escape an interview, but she'll still have to submit a statement of intent/proposal and a selection of essays, which will kill her chances pretty quickly, I think.
Her sample essays will be judged with much closer scrutiny by Oxford admissions than Exeter. Factor in the grade inflation and most of her Exeter work would likely be a 2:2 by Oxford's standards. They're much less likely to overlook Ruby's sheer overreliance on other people's ideas and writing essays that are 85% supporting quotes.
And the statement of intent/proposal will kill her chances immediately. She's never once been able to explain why she wants to study English at Masters, or why she wants to go to Oxford outside of it being "the BASST". They're not going to be remotely impressed by her waffling purple prose romanticising of Oxford as the Dark Academia dream which she's wanted since she was 6, or by her using her high school teachers as references, which she's bound to do.
Jack Edwards had the exact same issue: He graduated with a First, had the grades for Oxford Masters and was an easy sell from his academic history, but was quickly rejected because he approached his application from that route of superficial entitlement. He could never articulate why he wanted to go to Oxford or what he hoped to get there which he couldn't learn elsewhere (or independently). He just wanted to go to Oxford because it's socially viewed as "the best" and he felt entitled to it (and cited his vanity book and that vapid Sixteenth podcast as reasons why he should've gotten in), but had zero actual interest in studying.
Plus Ruby has a consistent pattern of trying to recycle all her old work, so I'm sure she'd try reusing the entirety of her undergrad dissertation as her Masters thesis. They'd toss her application immediately.
I totally agree, whether she gets in or not, a Masters would be the worst idea possible for her. She'll be completely out of her depth, she won't learn anything and she won't use the degree for anything after, so if she has any sense she'll just quietly abandon it.
This just in: Ruby's had some very disappointing raspberries, but they're *okay*.
Translation: They weren't gifted.
If they were, those exact same disappointing raspberries would be "SYO GOOD!" and her "FAVOURITE RASPBARRIES AVVER!"
