The point is that you can be free to be yourselves and not molded into what someone thinks you should be. Don't think you have to buy a packaged curriculum. This was the biggest hurdle for me to overcome. I would spend money that we didn't have to buy high priced books. Save your money and use the library.
Real books are so much better.
If you're having problems with English or math, try a tutor. I realize that not everyone can afford a tutor, including me. That's why I barter for services. I have made meals for science lessons, cleaned house for computer lessons, and exchanged educational help in one area for another. There are people out there with all kinds of knowledge just waiting to be asked to share what they know.
