So I thought for a reference you are meant to get a previous tutor/lecturer. I asked one of mine and he hasn't replied. I have a feeling he feels like it's too long (15 years ago since I did undergrad). I could try a couple of other tutors I've kept in touch with who could say a couple of nice things but I'm sure all recollections of my time in class will be a bit murky.
Who is best to ask and who have you asked? Thanks!
