^That’s actually not a bad idea, ucbalumnus, although I can’t force students to drop the course. I CAN give them a “math quiz” in the first lab and strongly suggest that those below a certain level will be more likely to succeed if they take more math first. Kids that age are prone to “magical thinking” as we all know, so not sure how many would actually take the advice.
The worst thing of it is, if I could get them to ACTUALLY DO WHAT I TELL THEM, most of them would survive the course. Leading horses to water, as they say.
