Ali,

Thank you for your message! :) With the transition lessons, honestly you can work at your child's pace. We have many families who say that they speed through the first few lessons because they are concepts that your child knows, but we are teaching them RightStart™ methods.

Also take note that the beginning of the book on the index page you will find a listing of all the lessons, this will show you how far to go to be up to date with Level C.

I hope this helps! Let us know if you have any other questions, we are glad to help! :)

Make it a great day!

Cassie
