My D isn’t in engineering, biological math. She is trying to decide whether to do Bio+Chem+math (Calc 3) 1st semester, or to just do 2 of those 3. She will take something else (like psych or anthro) too. On the Biosciences advice page, they recommend 6-8 credits math/science per semester. But Chemistry is such an essential building block for later courses, I hesitate to have her put that off.
