Like for example, after I find out my grade for an exam, and I don’t get the score that I want, I get envious or jealous when a friend or acquaintance gets a much higher score than me. It just makes me feel like they’re better than me, smarter than me, more competent, etc. How can I not let other people who get a higher score than me on an exam, make me upset?
Don’t exchange grade information with friends.
If you studied more, do you think you could do better? It may be the case your reaction is because you think you could do better. If not, you need to find a way to be comfortable with who you are. No matter how smart you are, you can always find someone else smarter. Comparing yourself to everyone else and wanting to be better is just a recipe for unhappiness.
Be yourself. No matter what happens they can’t take that away from you. And understand you are often your own worst critic. You may find different people who beat you one each test but you are beating some of those same people on other tests/in other subjects.
Your need to evaluate your whole self, not just your performance in one area. Someone will always be better at pretty much everything but nobody will be better at being you.
If you feel jealous of a friend’s grades, ask them about how they study and prepare. Maybe you can study with them. Sometimes, rather than envying someone, it’s easier to learn from them.
