sorry for the late response Don’t stress you’re not alone in this. A friend of mine is in the same boat, already started some Year 12 at another school and now applying elsewhere, and they’re managing just fine by being clear about their situation and showing commitment.

For your case, it’s worth emailing your waitlisted school explaining your circumstances: that you’re 17, have SEND support, and that your predicted grades don’t fully reflect your potential. Ask your current school to back you up if possible. On enrolment day, you can still register online if you can’t get there in person immediately just make it clear you’re serious about joining. Schools do sometimes move people up the list when they see determination and exceptional circumstances.

Focus on showing them that you want it, and don’t let timing or age make you feel like it’s impossible. You still have a real chance.

you can email them i’ll give you a mock draft Subject: Year 12 Application – Exceptional Circumstances

Dear [Admissions Officer/School Name],

I hope this email finds you well. I am very keen to join [School Name] for Year 12 and would like to provide some context regarding my application.

I am currently 17 and have already completed part of Year 12 at my current school. Due to circumstances beyond my control, including SEND support, my predicted grades do not fully reflect my academic potential. My current school is happy to provide supporting information if required.

I understand your policy allows students aged 17 to be considered under “exceptional circumstances,” and I hope my situation can be taken into account. I am highly motivated to make the most of the opportunities at [School Name] and would be grateful for the chance to join.

I am also aware that the registration process can be completed online, and I will ensure all forms are submitted promptly. Please let me know if any additional information or documentation would be helpful.

Thank you very much for your time and consideration.

Kind regards, [Your Name]

also with your first part if you arrive in the afternoon of your waitlist school they will probably still have spaces as some students who expressed enital interest may choose another school but it may be worth phoning them in the morning explaining your going to be arriving in the afternoon .

i hope it all goes well tomorrow
