So my history teacher has told us that we aren't going to do this topic and is contains very little facts and is 'mostly common knowledge'. Having not studied this I don't know if this is true, is it worth studying?
Yeah, I think it's definitely worth looking at as it does come up every single year and it's very similar questions that are asked. Besides, it only makes up one chapter in the history textbook, so why not? (at least that's the case with mine - An Cúrsa Iomlán Staire - perhaps yours is different :/ )
