Hi Rozia. In 2011 I completed a fast track A Level with Oxford College which is a distance learning provider. They are pretty good but you have to arrange exams and pay for them separately.
I have recently enrolled with Open University to study Law which starts in February. They provide a great deal of support, offering tutorials and tutor support throughout.
My Brother-in-Law completed an LLB Law with the University of London International Programmes who are also a distance learning provider. Whilst they are a prestigious uni, they only provide a study guide and reading lists, with no tutor support for some of their degrees.
Hope this helps, let me know if there is anything you want to know
