Twins’ school has an odd science path. 9th was Chem 1/physics (1/2 semester each). After that, self-selection. Twins took Chem 2 over the summer and both are in AP Chem now. D21 plans to take AP bio next yr, 11th. But S21 is thinking of taking AP Physics C (full yr/both parts) instead. He’ll be taking multivariable calc next yr (in BC now).
My question is: Is there a problem with not taking any biology until 12th grade? (He’d take AP bio 12th). It seems weird to me, and when looking at summer science programs, some required bio. But, other than not qualifying for those, is there a reason for him to switch the sequence he wants?
Neither twin knows what they want to do in college, but math, and science related to math, comes naturally to D21.
