Yeah, I said before we should prepare ourselves that she's going to get accepted. The main reason is that they don't actually have to speak with Ruby, i.e. an interview, to make the decision. Trying to memorise her way into Oxford as an undergrad caused her to bomb the interview.
But provided they don't actually look into her background and watch any of her youtube videos (or read her ghastly novel), Ruby looks very good on paper. We know from her firsts at Exeter that even though she takes critical feedback extremely badly and seldom seems to accept it, when it comes to her academics she is both willing and able to "play the game" by implementing it. And she will have probably had someone look over her application to fix any problems, as well as learned from her previous applications. This is almost certainly her third attempt at getting into Oxford and her second attempt at getting in for her masters. She had it the applications on her to do list last year, and then we didn't hear anything until she said she was taking a gap year. Knowing how obsessed she is with Oxford, there's no way she didn't apply last year because that would be giving up a chance. As we've seen with Jack, there's only so many times she can keep reapplying. She'll have learned from Jack's mistakes too.
So she's applying with excellent marks; likely excellent references from those tutors who gave her firsts; an application that will have been carefully crafted, ruthlessly edited, and proofread (unlike her novels); and although it will matter less to Oxford tutors, claims to have run a successful youtube and stationery business. The trip to America was also likely with the application in mind.
The annoying thing is that she'll take this as vindication that the tutors made a mistake and didn't recognize her brilliance during the undergrad interviews, or just put it down to her nerves like she explained away her lower-than-expected A level grades. Nothing to do with her appalling preparation, though! I wonder how many of her impressionable teenage followers failed to get in because they followed her dreadful advice.
