Learning subject outside school- predicted grade?

Hi everyone,

I am in the process of sending off a late UCAS application, but I currently am learning AS Mathematics outside school on my own and do not have a predicated grade. What can I do this about this or let the universities know about this?

Thanks

Are school not able/willing to give a grade?

Could you show them some work/do a test and get them to say something?

I will have to ask them, and see if they can include it on my reference.
