Well, yes and no - I've accepted that they're a necessary part of the learning process, and they're exciting when you think you'll do really well, and when you're actually writing them it's the best feeling ever when you feel like you've got it and you can't wait for your tutor to read it. However, (especially at A-Level when merely knowing the content is not enough), revision is very stressful and in all of my subjects you have to be writing literally every second otherwise you're just not going to have enough time!!
