Yep, it's the worst feeling. But make sure you take time out of revision etc to do things you enjoy. Try and find something to motivate you when you're in class / revising, such as an image of what you'd like to be when you're older, that always motivates me to try my very hardest. Everyone dreads exams, but the majority of the time, you will have achieved a good grade, so don't stress too much! I've only done one exam so far too, remember it only gets tougher from here, so try your best to be strong! X
