I've actually completed my A-levels and one of them was Classical Civilisation. It is well respected, although I agree with some of the earlier comments suggesting it is easy. However, it's only easy if you are prepared to memorize every detail of the set texts; as a matter of fact you get 20 marks in your first year from just being able to recall the plot. It's really on a par with English Literature in terms of writing skills – which is another subject I coincidently took - but with a more direct focus on the culture of ancient societies. If you really want to be challenged at A-level I'd actually recommend taking Philosophy though it is incredibly demanding. Possibly the only A-level which had any intrinsic worth for me though.
