Third, for subjects like Physics C: Electricity and Magnetism& Mechanics, I prefer to prepare lessons before the class. Well, you might feel it is the same old shit again. I am not an expert of physics, so I always use Princeton as my textbook to prepare for the upcoming class. If you have a specialty in physics, there is definitely no need to prepare for the class at all. A big part of Physics C is based on senior high physics and calculus, so if you have time to review your high school textbooks and ‘just-learned’ calculus would be the best. I personally think some practicing questions in Princeton are more difficult than those in the real examinations. But do not give up practicing those challenging questions, because those questions are perfect materials to test whether you have mastered the class or not. It would be better if you can redo those challenging questions some days later.
第三点,对于物理C:电磁/力学这样的学科,我偏好先预习再听讲。你或许觉得又是老生常谈的东西。我不是一个物理专家的人,所以我会使用普林斯顿作为我预习的材料。如果你是一个擅长物理的人,自然就没有必要提前准备了。物理C的很大一部分都是建立在高中物理和微积分上的,所以如果你有时间在课前重温一下高中知识和刚学会的微积分就再好不过了。我个人感觉普林斯顿上的某些习题难度大于真考。但请千万不要就此放弃这些具有挑战性的题目,因为这些题目是检验你是否熟练掌握已学知识的完美材料。当然,如果你可以做完这些之后过几日再做一次便更好了。
