Private Candidate refferences

I'm having to resit a year due to lack of attendance at my sixth form, so I've decided to do my exams as a private candidate. Other than my attendance/punctuality I was a relatively good student. The problem is I'm wondering if I can use my old sixth form as a reference despite shortly joining a new college (I left quite quickly).
If anyone has experience at London Brookes College that would be helpful.

What are you wanting the reference for?

For applying to a Uni in the future.

Well, there's hundreds of things you could want a reference for, and your post made no mention of university.

You will need to speak to your old sixth form, but it is standard that they will provide a reference in these circumstances. You will need to check if they would mention your lack of attendance - they most likely won't, but they would be entitled to.
