A *strategy* to read classics? If you need a *strategy*, I suggest you read something else. It sounds too much like effort.
Anyway. Jane Austen is clearly good even though I've only read the first page of Pride and Prejudice. For Shakespeare, Midsummer Night's Dream is easy. I don't know why some Shakespeare is hard and some is easy. I can't get into Dickens. Some times I can't even understand him! H.G.Wells is better than you think
Oh, and Wuthering Heights is a wild, strange kind of book.
