Whether or not you think you'll need a tutor someday, I highly recommend Kumon or its equivalent in your area. We pay $88.54/month for four hours/week at Kumon and all the calculus worksheets she can handle. It's the equivalent of Suziki musical tutoring for math & reading with the kids doing far more than one would expect them to be able to accomodate.
Yes, she's in ninth grade and she's doing Kumon calculus (along with her high school geometry homework). Because she asked, the high school has agreed that she can skip next year's Algebra II course and go straight to Trig. She'll do calc in 11th grade (the school won't allow validation) and cap it off with senior AP Statistics. By then she'll also be doing Kumon's differential equations. I joke about adding in partial diffeqs & other engineering math but I'm not sure that they're joking. "Helping" her with Kumon problems has been quite a challenge to our perishable math skills, too.
The owner of her Kumon franchise has also employed her-- six hours/week at $7.25/hour. There've been many educational moments around that lifestyle change, too.
She's been doing Kumon since 2nd grade. It seemed like a lot of money at first but the progress and the testing confidence (to say nothing of the GPA and the college savings) have been phenomenal. We never would have started Kumon but it's what a significant minority of kids do here (both for math and reading) and she wanted to be with her friends. Most of them have dropped out of the program now but she's really blossomed with it.
