High school student Lin Zhixia failed her mock exam, scoring only 58 in physics and dropping to 426th place in her grade. Facing the gap, instead of blindly drilling questions, she broke down her mistakes and rebuilt her study plan with the help of her deskmates Xu Ning and Zhou Yuan. Her head teacher, Teacher Chen, encouraged her to use logs to test her progress, and her physics score rose to 86. However, abnormal data in an experiment made her realize that scores are not the end of exploration. Under the guidance of Teacher Luo, she conducted control experiments, retained failed results, corrected hypotheses, and showed her potential for scientific research. When exam week arrived, she learned to reasonably arrange review and inquiry, no longer panicking when facing old mistakes.
