Has anyone gotten into Oxbridge with a 2:2 & High Masters?

You have achieved recent successful postgraduate degrees. So you should be a 'competitive' applicant for Oxford. 🙂

If you submit evidence of the ECs, your application can be considered in light of them. Oxford postgraduate application has a section for this. And they say on their website that they'll consider someone below the minimum if they have ECs. Usually, you need to prove that you submitted these ECs to your undergrad university first and they were unable to take them into account. What Oxford can do is place higher emphasis on grades where you weren't affected by the ECs, what they cannot do is guess what you would have gotten.
I would also add that it matters what you're applying for. Oxford usually says they want a 2.1 minimum mainly bc they need to be wary of the fact that a high 2.1 from Cambridge ( and maybe imperial) is the same as a 1 from a slightly less competitive university. It's also true that for some maths programs, a strong masters degree can satisfy a 1st class requirement if not achieved at bachelors. So perhaps your strong masters requirements can override the undergrad. All in all, I think playing a guessing game doesn't help. I would say apply for the program. Submit your ECs. Write a strong statement and leave the rest to fate.

Thank you for saying this. Do you speak as a student there or you feel that that showcases I'm competitive? Some of the Masters courses will say, even if you've gone on to have professional experience or achieved higher in postgraduate degrees, they wont consider your 2:2, which is beyond discouraging.

Hey Everyone,
I am trying to apply to Oxbridge next cycle for an MSc or MPhil in Development/Policy/Social Studies/Law... not looking at Doctorates just yet and I need some advice, reassurance, or clarity based on my background and my prospects, if you could help.. I'd be most grateful!
Some background:
I've had a somewhat non-traditional background because of some poor financial mistakes that took me out of the University of Toronto (I'm Canadian) for my BComm to the online University of London Programmes (with LSE) for my BSc in Development, which I finished during COVID with a 2:2.
I had exentuating circumstances (parents both lost jobs so I had to work full-time and finish my 3rd year full-time) and my grades ended up dropping from a 2:1 in Y2 to 2:2 in Y3. Nonetheless, I pursued a Masters at a private French Institute and got a Distinction there in European Policy and IR. I then did an LLM at Leeds Beckett (Law Conversion) also in a Distinction and then did my Masters at Harvard Extension, also Distinction.
I have participated in 2 research projects (no published papers), and work intimately with UN organizations in the advocacy space.
I'm really hung up on this 2:2 and Oxbridge makes me feel like no one will look past my poor mistakes. I really want to prove to myself that I can do it and that I have a shot to achieve my dream - if anyone can share any success stories, I would be most grateful.
