No reference

Ask around your family and friends to find out if anyone is in a professional role and willing to give you a personal reference. Ask your faith leaders. Ask your doctors/health workers. Ask more teachers (and try asking the ones who refused if there's anything you can do to change their mind). Employ a tutor and ask them.

I'm on my own, my parents are unemployed with no education. I have no uncles or aunts or anything like that. Teachers have stopped replying to me. I have no one.

Email your target unis and explain your situation. They may have suggestions for other acceptable referees or if you are lucky, agree that you could submit an application without a reference.

One of my target unis is a Russel Group one - uni of Southampton. I doubt they want to take me in without a reference, even though my predicted grades are AAAB

I work at a RG uni and in some exceptional cases we have accepted people without a ref. Just email Southampton to ask. They're there to provide guidance to potential applicants.

NB. Where have your predictions come from if you are not being tutored?

I have online tutors who grade me, but because they are online tutors they won't provide me a reference as they don't know me 'in real life'. The organisation I study with gives me lessons and they grade my tests and mocks, giving me predicted grades.

Hi, if I get a tutor for this year, do you reckon they’ll give a reference in such a short time, without having enough time to know me? Plus what if they refuse? Could you please help me on how I can go about this, it’s already end of October and I’m panicking more by each passing day.

I have no idea what an imaginary tutor will or wont do. You need to actually talk to the people who you would like a reference from and find out what information they need to feel comfortable providing you with a reference
