What you could do is get a really good revision guide, there's plenty of books on Amazon to get you through the year and just do timed essays.
I did AS Law last year practically self taught and got 96% on the papers altogether with dropping only 2 marks on English Legal System.
I'm thinking of writing a revision guide for OCR Law for AS Level structuring the essays (basically giving you the essays to revise from) do you think this would be helpful to you and other people?
