So my DS is a junior and currently taking AP Physics C. He is doing fine in the class, an A, but is considering taking it again next year for several reasons. The main one because his teacher does not think the class will be prepared enough for the electricity & magnetism test. He has offered to hold some study groups and allow my son and a few others the option to self study and still take it but he has 5 AP classes this year so he's already pretty busy. The other reason is he is kind of out of science classes to take. He could do AP Bio but he doesn't really have any interest. So my question is would it look bad to admissions if he retakes it? If he does he would still mostly self study for the E & M test but he would have all year and overall a less demanding schedule. Or would he be better off self studying this year for that part, or just letting it go and taking AP Bio? Thanks!
