obvious choices are: english literature (tends to be preferred over english language by the top unis as far as i know), history is always a winner when taken with english. I chose those two with maths and politics, and feel i had a good mix which complimented each other well (maths was a relief tho, wouldnt want to do 4 essay based subjects!).
not really any subjects I'd flag as 'do not take', not without knowing you anyway. Psychology tends to be one that people either love or hate, based on the amount of facts there are to learn. friends tell me law can be quite dry. But this is all subjective! choose what you think you'll enjoy enough to get good grades in!!
