~what i do when i fail~
When you fail at something (a test, an exam) it means you did something wrong. You don't need to be stressed about it. You can learn something new when you fail (example: when you do something wrong you will know it was wrong and the next time you wont do it again).
Don't worry about what others say when you fail, they are not helping you in any way and dont listen to them. If you do, you wont trust yourself and you will be more quiet, and that is bad. Dont worry if tou fail, if you wanna say something when you are in school, just say it. Even if its wrong or bad. It helps you be more motivated and it makes you trust yourself.
