Homeschooled looking to study in USA - Predicted Grades

Hello,

I am an A Level student supposed to be in year 12, however I am studying my courses privately instead. I am looking to apply in 2018 and being already familiar with the USA College application procedure, I just wanted to know how a student would obtain the predicted grades needed to give the universities as I am not in a school that would give them.

Thanks

Answers appreciated

Yes, they are there to mark the occasional assignment to make sure I am reaching the grade I want however do not help me beyond that, I teach myself completely.

perhaps they could predicted grades for you?

I didn't think they would have as much qualification as a school for example. But thank you!

They don't need to be a school. So long as they are an independent person (e.g.. not your immediate family) it's fine.
