Most of it's common sense to be honest and then a lot of religious quotes to reuse. I'd say no, unless you like disappointment. It's an easy subject mostly but there is just a lot a lot of information and random crap to remember like the reasons for a just war and random articles from law. If you somehow managed to get away without doing it in yr9 then isay don't bother there are a lot of other subjects you need to do well in
