1. The Importance of Calculations in OCR Physics | 计算题在 OCR 物理中的重要性

Every year, OCR publishes analyses showing that students who practise calculations methodically score higher overall. Calculation questions appear across all papers, covering topics such as forces, energy, electricity, waves and particle models. They reward careful working, correct use of equations and solid unit manipulation — skills that transfer well to the UK A‑Level sciences.

OCR 每年的考试分析都表明，系统练习计算题的学生整体得分更高。计算题分布在所有试卷中，涵盖力、能量、电学、波和粒子模型等主题。它们重点考查解题步骤、公式的正确使用和单位转换 —— 这些技能对将来学习 A‑Level 科学课程也大有裨益。
