Have you ever been so stressed about one test that you're concerned it may ruin your whole life? Let's say you can't understand one concept, which means you'll fail the test, which means you'll fail the class, which means your GPA will drop, which means you won't get into a good college, which means you won't get a job, which means your whole life is over. Not exactly; you can calm down.
While school may seem stressful, between AP classes and extracurricular activities, it's actually okay if your worried, and, believe it or not, it's okay to do poorly on a test. Personally, I am always studying as much as possible before tests to make sure I get an A and keep my grades up.
But if you step back, and look at the big picture, that one test is not as important as you may think. It's one test, in one class, in one of four years of your high school or college career. It won't even make a dent in your GPA. So if you're unbelievably stressed, and freaking out, remember that it's okay to go to bed, get a good night’s sleep and just do your best.
Now, don't get me wrong, studying is important, and grades are important. If you don't study for all of your tests, of course, your grades with drop. But when you're in a situation when you have too much to do and not enough time and you are totally lost as to what you should do, remember that one test doesn't matter. Pick a test to study hard for, and relax about the other one. You'll survive, your life will not be over. I promise.
When you're in these tricky situations, it is hard to stay calm and to realize that you're freaking out over nothing. But just try to remember how many other tests you've taken and how many more you will take, and that this one is just one. Just one test that's ok to mess up on once in awhile.
All in all, remember that high school is not supposed to be that hardest thing ever. It's supposed to be fun. So don't deprive yourself of sleep, have anxiety attacks, or weekly rages because of school; instead, relax a little. Study as much and as hard as you can, but remember that it's not the end of the world if you mess up once.
