夏风吹过 发表于 2025-05-02 14:09 AP Chemistry难还是AP Physics C难,高中生应该先上哪个
这个问题取决于学校课程安排。有些学生觉得AP Chemistry更难,有些学生觉得AP Physics C更难。 我一贯主张,先上high school chemistry,再上AP chemistry。FCPS high school chemistry是10年级,必修课。 我也一贯主张,先上high school physics或AP Physics 1, 再上AP Physics C。FCPS high school physics是10-11年级,选修课。 我反对很多TJHSST学生不上high school课程直接上AP课程。

虾老师,每年都出来吓人
这考的是物理,还是考微积分啊。。
这题我会,物理好的人数学一定好,数学不好的人物理一定差,数学好的人物理不一定好!
我的一部分AP Calculus BC的学生,学校老师进度慢,还没有学到polar coordinate system,所以他们在AP Physics C电磁学复杂的Biot-Savart定律积分翻车。
再就是我所有AP Calculus BC学生包括TJHSST学生,学校微积分老师今年终于把Calculus BC不考的cylindrical shell积分删除了,只讲disk-washer积分,但今年College Board AP Classroom AP Physics C E&M样题的Gauss定律积分题目全部是cylindrical shell或spherical shell或双重积分(电荷密度不是均一的,而是一个其半径r的函数或其x-y坐标的函数)。结果是我所有正在学AP Calculus BC的学生全体翻车,而所有正在学或已学完multi-variable calculus的学生全体成功。
今年AP Chemistry和Calculus BC不会比去年难。
今年AP Physics C是考微积分 。
Calc BC倒数第一章或第两章的极坐标积分,BC十多年前删掉的cylindrical shell和spherical shell积分都变成了这次AP Physics C考察重点。
对头!

时间大大延长了,但是AP Classroom里面的样题无论MCQ还是FRQ都是大量积分和微分方程题,连我都做得很慢,我手头有TI-84计算器和Desmos。
我们physics 和 chemistry 都上过了,在考虑明年先学哪门AP
你没有仔细看, mcq多选题取消了,全部改为单选题,而且从5个选项改为4个。
不排除题目难度加大了
如果将来学医/制药/牙医/兽医,肯定是AP Chemistry。
如果将来学工程,肯定是AP Physics C。
至于将来学数学或计算机是否要选AP Physics C,我请教过一个数学博士,他说:他高中学过AP Physics C力学和多元微积分,所以大学数学系不用再选微积分力学这门必修课,而大学数学系根本就不要求微积分电磁学。
我们学校就是这样,先AP物理1 ,再AP化学,化学要先修honor,最后AP 物理C,一般物理C都12 年级选了,同时学多重积分。
谢谢解答🙏
谢谢。那照你这样说法,以后学数学和经济应该是先修A P物理好些吧
学经济的本科根本不用学物理。
学数学的本科必须学一个学期基于微积分的力学。
学还是得学的呀,11,12年级各一门
