For me it would have to be OCR ICT. I also took Computing, Physics and Maths, and want to study Computer Science at University. The coursework for ICT took up pretty much all of my time, even though I am predicted 90%. The theory was also very dull to learn, and difficult to remember because of how dull it was. ICT also has no relevance to Computer Science at any of the Universities I want to apply to; I should have taken Further Maths instead. I probably will pick up the AS Further Maths next year alongside A2s in Computing, Maths and Physics.
