General Physics II · Midterm Preparation
Exam scope（考试范围）
- Chapters 1–14: electrostatics, conductors, circuits, magnetic fields, induction, oscillations, and electromagnetic waves. 理论内容均在范围内，老师未公布各部分比例。
- Formulas will be provided. Practice choosing a law, checking its conditions, setting up an integral or equation, and interpreting the result.
- The 2023 paper illustrates question styles and breadth. 今年不重复原题；旧卷每题 25 分不能用来推测今年的分值分配。
- Chapter 15's reflection/refraction is outside the stated chapter boundary. Electromagnetic waves in Chapter 14 remain required even though the supplied 2023 questions do not test them directly.
