So what you're all saying is I have to either choose one or the other-piano or highschool-and there's no way to do both? Well that's a tough decision, and I don't really know much about homeschooling and I generally have a good time in higschool (call me a geek, but yes, I love to learn new&hard things)...and I know my parents would kill me if i dropped out... I wish I could be a 5.0 student and be the great pianist I know I could be if I had time.....but maybe it's just not possible? This is so depressing...
It's possible to do both. You must be extremely efficient with your time and energy, however, as you might have guessed. You know whether you are already being as efficient as possible, and if you are, then you know whether it is possible for you or not. If you are not, then buck up laddie, there's still hope! Organize, organize, organize. It mostly depends on you.
Take an honest assessment of how you spend your time. Cut back in the areas that don't matter as much to you to allow for the things that matter more.
Find an average of how much homework you have each day. Think about which subjects need more attention, which subjects will help you learn from the other. Organize your homeworks in a way that one aspect will help the others, if possible. Don't study the things you know you already understand and will not forget. Make sure your environment is extremely conducive to concentrated effort. While you are on a break from reading, clean your room. Organize your practice sessions thoroughly.
Get a detailed calendar that has the week at a glance and breaks down each day into 15 minute segments. Prioritize.
Talking with your parents, guidance counselors and your piano teachers are great ideas as Sharon suggested.
