Tackle the reasons why you doubt yourself. Trust me, you’ll survive. Teachers and schools put so much pressure on you. Just remember it’s not aimed at the people like you who get wound up about it. It’s for all the thickies, to try and motivate them to do work. However pressure does the opposite to most people, in motivating them. You’re very likely to sail through and pass them all. I thought I was going to get a 3 in a certain subject. I got a 5. I came out of one exam crying. I then got a 9 for that subject. GCSE’s are so hyped up compared to what they actually are. I hope this helps! Xx
