As a private student that pays my own entries I've realised not to fall back on retakes because they're bloody expensive. 50 quid per paper because I have to pay an extra admin fee too. It's taught me to put 110% effort in first time round.
Mine are exactly £25.00 per module , which is quite high. I remember seeing the OCR prices for entry and they were roughly £13 or so for a module so I don't know where the extra £12 goes, probably towards the school's finances.
I think it is ridiculous. In my college they initially cost £30.00, for what an extra paper? And then it goes up to £50 and then £70 in a short term period. What is worse is the people who took January exams had only little more than a week from results to decide whether to retakes before the price went up from £30 to £50
