MAJOR QUESTION about teacher references

Can I ask a teacher who does not teach me a subject related to the major I want to pursue to be my reference? I am going into law and I am applying through early decision so I need to ask a teacher now. I've asked my guidance counsellor, who is really useless, if I can ask a teacher other than English and Geography...she doesn't know.

I'd like to ask my science teachers or my French teacher....is this recommended? Especially since they are my better subjects and I have better connections with them?

I'm not clear whether you are applying through UCAS or in another country? 'Early decision' sounds like the US to me! You can have any teacher you like as your referee for UCAS as long they can comment on your academic performance all round.

Oh yes I applying through UCAS but I am an international student. Oh I'm not applying to the US...it's just that the school always talks about it so I got mixed up...I think in the UK it's called the early admission scheme...not sure.
So, even for the UK, it's ok if I don't choose an English or social studies teacher as my reference?

What usually happens here is that an applicants personal tutor writes the reference having consulted with everyone else who teaches you. The personal tutor might not actually teach you at all, in that system!

I'm still confused about the 'early admission' scheme though....

I will be applying to Oxford or Cambridge so I'll have to apply earlier than usual...I belive before October 15th. Oh in my school (in Canada), we don't have a personal tutor to write our personal statement, we have to get a teacher for our reference.

My reference was written by my head of 6th form who only met me once, and shouted at me for missing assembly. So, yeah, any teacher can write your reference!
