Thanks for your replies. My takeaway from your comments is that you don’t have to be a genius at math to do well in CS, just be decent. BTW, I said “bad” at math because her high school has some kids who really are geniuses at math. She’s not one of them, her gift is in languages. She’s on the normal math track (AB calc senior year) and does well. For the ACT she had to study for the math section so she could pull her score up from the 87th percentile, but she didn’t study for any of the other sections. My concern was if she goes into a field that is very math heavy, and if she wants to compete at the highest levels, I don’t think that would be a good fit; she does not have the natural talent that some of her classmates have. I also think she’d be happiest if she chooses a path that fits with her natural talents, and wasn’t sure that CS does once you get into the upper levels.
