Feel like I'm unfairly being classed as an EU student by Scottish universities

Ok. All Scottish unis have different policies when it comes to classing EU status.

For example: St Andrews classed me as EU simply because my father, also N.Irish, has an Irish passport. Literally, that was it. And I was born in London but have lived majority of my life in N.Ireland. (And now I hold one too, since I technically have dual nationality, perks).

BUT Dundee and Glasgow classed me as RUK because I had not physically lived in Southern Ireland for more than 30 days, regardless of the Irish citizenship I hold.

OP, I would speak to St Andrews and Edinburgh

That's strange. Might that be because you were living in Northern Ireland at the time? I think the OP said they live in London, so having an Irish passport (or their mother having one) shouldn't make them an EU student. I am a dual British/Irish citizen but when I applied to two Scottish universities (Edinburgh and Aberdeen), they both said I would pay RUK fees because I was living in England.

I'm not sure, can't remember.

I've applied to both Edinburgh and St Andrews. I applied to Edinburgh last year and was unsuccessful, having been predicted A*AA for maths (which last year was a standard AAA-now been boosted I believe to A*AA, not that bitter ) However I was classed as an EU student, because of my mother's Irish passport. At the time, the idea of paying 2.5 grand as opposed to 9 seemed attractive, however when I didn't get an offer, a part of me thought I was short of the standard required, but another part of me thought that it was because I didn't make the quota for EU students.
I'm British-have a British passport, was born in London and have spent all my life in London. My dad is British, born in England and my mum is Irish, born in Northern Ireland. I know that if you wish universities to reconsider your fee status you must write to them, but I probably qualify via some rule for being an EU student. Does anyone else think this is unfair? I'd happily pay 9 grand since I could end up paying that at 3 other places.

Your not an EU student. Past 2011 Northern Irish Students cannot use Irish residency to claim EU fee status.

There is no quota - EU students battle for the same places as UK - it would be illegal to disadvantage EU students for university places. You're confusing it with international students.

There is a quota - Scottish universities have strict limits on the number of Scottish/EU entrants they can admit. There's no similar limit to international or RUK entrants as the funding for those students is not subsidised by the Scottish Government.

Hence why I'm eager to be classed as RUK

EU and UK students are counted as the same quota so it wouldn't have affected you application at all. I'm sorry to say, but you just weren't good enough.

Ring them up and explain that you consider yourself to be an RUK student (and will be applying for student support and finance from SFE to cover £9k fees). They should be able to tell if your fee status had an affect on your rejection and if so send you a fee status questionnaire.

PQ would know. PQ is an expert.

So I'm right then? They are classed together. Because EU law says that a country must treat other EU citizens in accordance to how they treat their own. Like in terms of education, healthcare, welfare etc.

I just want to know why you're prioritizing slightly easier entrance to uni over paying significantly less in uni fees?

Just rang Edinburgh and St Andrews. Ed told me yes you are EU, SA told me most likely RUK.
