I would have to agree with you. Today's school mostly teach outdated information and the information we will probably never ever use in real life. In other words useless information.
I am a college graduate and I hated to learn about information which I found useless especially for the major I choose. The colleges today have become a business and not a place of learning.
I admire your courage. Especially because I am sure you got some weird looks from people by doing so. It is not an easy thing to do. So hat off to you lady.
Have an amazing day and good luck with homeschooling. :)
