There were courses that I wanted to take as an undergrad, but couldn't until I'd met the prerequisites. I took the prerequisites. I've taught undergrads, and I see the point. I've had students who hadn't taken the required courses, but convinced me to let them stay in the class. It was a mistake. They lacked basic skills that other students had, which made it harder for them to learn. They also slowed the class down at times.
I know that each case is different and that there are some students who may have self-taught the required material. At the same time, the ACT is a multiple choice test, and the essay section doesn't reflect the real world of analysis and expository writing. Writing well for a middle schooler is a long way from writing well as a college sophomore.
Not knowing the specifics, my advice would be that she should take the prerequisites. They may not be as interesting to her, but the college has a right to require them and probably a good reason for doing so.
