So, although math isn't her immediate worry (Algebra II is definitely next year's course), would you substitute out the college trig or algebra course and/or stats for calculus?
It sounds like a lot of you would take physics instead of microbio/zoology/botany rather than in addition to. The real hesitancy I have with telling her to go that route is that she's sacrificed a lot of what she enjoys for toeing the line of what is going to get her ahead in college aps/scholarships already.
For instance, she dropped her speech/debate elective this semester (it is a one semester class that would have replaced the other one semester elective she had in the fall) for study hall b/c she was already saddled with hours of homework/night and didn't think that she could take another class with a lot of homework. She was planning to add it back in her sophomore year but, again, is going to have to pass on it in favor of physics if she takes physics. She also doubled up on science this year in order to make enough room in her schedule to take this zoology course next year instead of the std earth systems class that is taken in 10th.
I told her that an alternative might be to take physics at the community college the summer after her 10th grade year rather than in 10th grade. We'll keep looking at options and hopefully come up with something that works and makes her semi-happy.
