The key is to work hard at ordinary times, don't be nervous before the exam, and don't think too much about how good you want to do, which will only increase your psychological burden. Don't make yourself too tired, and make sure you have enough physical strength and a clear brain tomorrow. If you want to continue preparing for the exam, you can look at some classic topics and keep some good ideas in your mind. I didn't want to do well in the exam at all, just casually and heartily, and got the first place in three cities! I believe you can do it, too. Come on!
