Just wondering, because my school never actually did.
You can ask to see your reference of course, I think they may have your predicted grades there.
but this year I think I got A for Sociology and French but Spanish...meh dunno I never go
The school gave me mine, albeit reluctantly. And if I hadn't been applying to Cambridge, it wouldn't have been nearly as glowing. =D
You've actually got a right under the Data Protection Act to see any information about you that is passed from one place to another. That includes your UCAS reference and predicted grades - so, provided you ask (in writing if necessary), they have to give them to you.
In reality the data protection commission or the information commission or whatever they call it these days are fairly ineffectual at helping individuals. The time I did try and contact them about an issue they didn't even return my enquiry. I am not impressed.
