Course selection junior year

My D is going to be a junior in high school, and she will be finishing the highest level of the science track this year. She is concerned whether she should take another history course this year instead so that she will have a science class senior year. She’s academically gifted and had no problem handling her coursework the past two years. She has an interest in STEM and wants to go into biochem/biophysics/molecular biology.

Any advice would be appreciated.

For college admissions, it makes no difference to them if she does 4 science credits in 3 years vs in 4 years. For her sanity, though, considering that she will likely be prepping for SAT/ACT, she should not take AP Chem and AP Physics C concurrently. But that’s a personal choice.

I agree that keeping Physics C for senior year would make more sense based on the possible schedule.
