I've looked high and low for videos about the CMEC. I've found people swapping their homeschooling methods from Classical Conversations to many other things, mostly critical, and I've found videos about the CMEC (Charlotte Mason Educational Center) in general for littles.
BUT, There aren't many videos especially for those who have both big families and older students. The largest family I found who does Charlotte Mason had 5 or 6 kids, but they were all elementary or their first one was entering 6th grade. My oldest is starting 11th next year! So instead of looking, now I'm creating.
I hope these videos help you if you're in the high school years and considering swapping to a Charlotte Mason education. I don't think it's ever too late to join into a delightful program like the CMEC. After all, if I'm a lifelong learner, I can change my mind when necessary.
