Purely anecdotical, but most of the women with a STEM education or interest I've heard from had a strong visceral dislike for calculus and strong attraction towards algebra . And not in the US. And also including mathematics graduates. "I'd take any abstract algebra problem/work anytime, just keep differential equations of all kinds away from me" was smth I've heard once if memory serves well... And at at least in Eu…
The track that should really take over should be one where the student develops the intuition about what related rates of change mean, and then abandon the chicanery of these special-case tricks in favor of the numerical solution of DiffEqs and the evaluation of the quality of the solutions.
