comes down to what you prefer. I've never been interested in ancient, but I like modern. be careful though cos I think whether or not you like modern largely depends on what course your class or school chooses for you to do, cos there's so many, like for one section you choose one out of 25 options. I remember in year 11 we did the civil rights movement in the 60s and that term modern was like my favorite subject, but then the next term we did cuba and i hated it so yeah... overall it's hard to say.
