That will depend on your school. For Modern History, both Year 11 and 12 consist of several electives. Within my own school, we had different CLASSES studying different topics. So there is no way of anybody knowing what you will be studying in Year 11, and while I admire your dedication, I don't think you need to prepare this early on for Year 11. If you actually want to go above and beyond, perhaps contact the Head of History at your school via email or phone, to see what topics you will be studying next year.
