Possibly, i’ll look into it.
If they don’t, the guidance counselor will HAVE TO state on the transcript or in the recommendation that the school does not offer any higher math class than Calc AB, so you won’t be penalized.
I agree. But just to make sure OP is covered, OP can mention the possible duplication of AP Calc AB (and any other issues brought on by the HS change) in the common app section where they have to address their HS change for 12th grade.
For OP, here’s what that section looks like. You have up to 250 words in the box to explain the reason for the HS change and any academic or EC impacts related to this move.
You stated that you will be attending an American school in your parent’s home country - if that is the case, they should have a college counselor available at the school to assist you. They will have experience with expats and students moving in and our of the school. If you can, I would recommend you reach out to the counselor at your new school and make an appointment upon arrival plus ask for guidance of what you should be gathering at your current school to assist with the application process.
