How much time do you spend on homeschooling?

I know that there are some parents who spend all day doing homeschool. However, we're simply not one of those families. We have found a comfortable way in which to only spend 2 to 3 hours doing schoolwork each day and yet my daughter is beyond her grade level. I know that I can't be the only one who doesn't spend all day homeschooling. So, how long do you spend homeschooling your child each day?
