For English Language I second Mr Bruff's You Tube channel, but it's also worth getting his booklet which is something like £4 from his website.
Learn the basic parts of speech, sentence structure, the technical devices including discourse markers, then why paragraphs are grouped a certain way. Most important learn to read what is inferred in the piece (i.e. what is suggested by the way it is written, but not actually put into words). For instance is the person described as bright eyed and bushy tailed meaning they are a happy person, or that they frown, are moody, dark and dismal for a depressed person or witch.
Also know what you need to do in each paper and what question, as they are similar, also the timings for each.
You'll need to know how to write an article, essay, letter, newspaper report etc.
PS I had to do a 10 minute presentation to get into the exam, so think on a subject you know really well to talk about and give a power point presentation.
PPS I found mind maps were brilliant, as well as cheat sheets all in a note book I carried with me everywhere and studied in every 5 minutes spare (ie bus rides).
