Hmm that's interesting. My timetable also says that my AQA English Literature Unit 6 Exam (the 180minute synoptic exam) is taking place on Friday 6th June at 2pm.
Check with your school or examinations officer ASAP. Also the exam units should be units FOUR and SIX. Unit FIVE was the coursework unit. It sounds to me that you may be doing English Literature SPECIFICATION B, whilst the OP and I are discussing Specification A.
Also, some advice on Lyrical Ballads: when you look at the poems keep Wordsworth and Coleridge's aims in mind (their aims are listed in an Advertisement written by Wordsworth [surprise] that should be in the front of your edition). They wanted to write about "human passions, human characters and human incidents". Look through all the poems with this in mind and it will give you a good starting point for analysis as well as links between the poems. This is only a stating point and you'll have to do seem deeper analysis, picking out other common themes etc, but it'll get you started and make things easier to remember.
