Tried to send this pm, but it wouldn't send. Anyhow here is my reasoning...
We decided to switch after challenge B for a few reasons. First my son was tired. It is non stop and didn't give a lot of time to go further into topics that interested him. It was difficult to scale down without falling behind. Second, it is difficult to add other subjects without falling behind. He really wanted to study Spanish and his tutor wanted him to continue learning vocab and rules for Latin so he could participate in class. Finally in the end his whole class made the decision to not return for challenge 1 and possible come back for challenge 2. They don't make it easy to adapt the program to your child's needs. I enjoyed the program and the discipline of it but it was tough and we just needed a break. To me it felt like public schooling at times with the learn it and move on without an opportunity to dig deeper into things. So that is my opinion. Like I said we may go back for challenge 2.
