I have started highers now (equivalent of A-levels) in English, Maths, Physics, Chemistry, and Classics.
Classics rules as long as you get taught about the good stuff. Learning about the Fall of the Roman Republic, the Spartans, the Pelopenesian War, the Odyssey, the Iliad, Alexander the Great, Caesar, Pompey etc will make it the best subject you will ever do in school.
However, don't let your teacher start wolfing on about columns and pottery. Mind you, I did do an awesome piece of work on the mathematical precision and ratios at work in the construction of the Parthenon.
