Are you sure they won't let you come back because of your english or is it because of your predicted as grades? I know at my school you have to get a certain grade to be able to do A2 (it's either a C or a D I can't remember) so are you definite its your english they won't let you come back because? Do either of your subjects require a pass in english for you to get the a level? I know a friend of mine is retaking her english GCSE and she won't be able to get her childcare qualification if she can't pass it. Maybe that's why they won't let you come back, its not because they don't want to its because they can't?
