Exams can make anyone feel nervous. Your heart beats fast, your hands get wet, and your mind goes blank (空白的). Don't worry — this is normal! Here are simple ways to fight exam stress, according to some scientific findings.
Breathe deeply. When worry starts, try 5 slow, deep breaths. Breathe in for 4 seconds, hold for 2 seconds, and then breathe out for 6 seconds. This calms your body fast. Maria, a ninth-grader, felt quite stressed out before her math test. She used this way and felt normal in 2 minutes.
Prepare step-by-step. Study 30 minutes daily instead of 3 hours the night before the exams. You can't review everything until the last minute. A UK study found students who did this scored (得分) 23% higher than last-minute learners.
Talk positively (积极地) to yourself. Don't say “I'll fail!” but “I've studied — I can try my best!”. Research shows positive self-talk lowers (使下降) pressure for 7 in 10 teens.
Move your body — even a 10-minute walk clears your mind. Share your feelings with friends or teachers if you feel too stressed out.
Nervousness is just your mind saying “This matters”. Use it as energy, not fear. Good luck and be wise!
