Shakespeare. For a start I think you'd be surprised at how much you can understand Shakespeare when you're going through it with your teacher - and as mine always says (I'm in y12 now, just studied Othello), you don't actually need to know all the details of what's being said as long as you can pick out the quotes you need, and they're generally fairly obvious or your teacher will point them out. There are lots of resources online as well to help you understand the Shakespearean english. You have a long time to get to grips with it - ultimately at least a year before you do it in the y13 exams. And Shakespeare is only one text out of something like six on the course, some of which will be post-1900 and therefore much, much easier to get a grip on. I wouldn't not do english lit just because of one text.
