I wonder if there is more than one group for the Columbia area. I joined the Ballentine group (north of Irmo) and my kids and I are really enjoying it. I know they are just memorizing, but I understand that eventually all that will pay off and when understanding comes, it will be cemented in their little brains.
One reason I joined CC this year is because I needed the accountability. I am strongly motivated to work on the memory work each week and to get all our school work done so my kids aren't behind when sitting in the classroom next to other kids.
I went into CC knowing that the teachers weren't going to teach my kids everything they need to know, rather they would plant little seeds and it's my responsibility to water those seeds each day.
Just thought I'd share my thoughts for others considering Classical Conversations.
