Well that's a really good sign that you're taking college classes (and high level ones at that), and it'll go a long way to show Adcoms how dedicated you are. Taking a college class during high school is much better than taking it's AP equivalent, you're really playing in the big leagues instead of just trying to represent a semester of a college class in an entire year.
Your senior schedule looks good, it actually looks like just my senior schedule was minus biotech, and plus anatomy and Virtual Enterprise. Go go orchestra... first chair percussion all through high school here!
And don't worry too much about your classes not being accepted, as long as they're not remedial classes, they will almost certainly be accepted at any school for your undergrad degree - and though unlikely, if they don't want to take it as a particular class that they have, you'll still get units. And remember that the GPA at one of your colleges doesn't matter, it's everything together. But again, don't stress, right now you're much better off than other high school students, so keep up the good work!
