Firstly, out your point and make it obvious, so the examiner isn't scouting your paragraph for clues as to what you're arguing. For example: 'Within Wuthering Heights, Bronte presents women as lonely'. Then, you would add your evidence, making sure it is embedded within ur sentence, rather than just put in ur paragraph pointlessly. Make sure to briefly explain your quotation and how it back up your point, particularly through word-level analysis and picking up on connotations to gain the best marks. Then, if the question asks so, add context as to why the author or poet has made their literary choices. Start with personal context. For example, continuing with Wuthering Heights, Emily Bronte perhaps presented women as lonely because she herself experienced loneliness within her life, being hidden away and not leaving her house much. Then, you would look at societal context or theoretical context such as the oppression of women during the 19th century or feminism theory, to make your essay as fully developed and evidenced as possible.
