I am doing an English Language (normal English) exam in a week, and I have no idea on the styles of writing! I know how to lay out formal and informal letters, and reports (a bit). PLEASE HELP! What other styles will I get asked?
Ask you teacher. Seriously. What else are they there for? They're the ones who are supposed to be helping you if you're stuck, and if you don't particularly like your teacher, try another English teacher.
