What Age Do You Use Progeny Press Lit. Guides?

I’ll be using them for the first time this fall. My then 11 year old will do one of the middle school ones (grade 5-8) on Anne of Green Gables. Then she will do on of the high school ones (grade 9-12) on Pride and Prejudice the second semester. She’s a great reader so I know she can tackle Pride and Prejudice and enjoy it. We chose the middle school one as our ‘getting our feet wet with Progeny Press’ book. She’ll adore Anne, it won’t be really difficult reading material for her, she’ll just be learning how to pace herself doing a PP guide.
