First of all, only you can know if something is right for your family. Sometimes one persons’s personal rant can cause you to second guess a whole curriculum.
We have used Queen’s history curriculum for years and I love it. But, I am not a history expert by any means and wouldn’t know if a few dates were wrong.
As far as LA is concerned. Sandi has raised a bunch of professional writers on that LA curriculum. I can’t see how it can be that bad. But, if your goals for your children are “more strenuous” for LA, then it might not be a good fit for you. It would really depend on what YOU think.
You can always do what I do – order the materials from somewhere like Rainbow Resource where you can return them without restocking fee and look them over thoroughly for yourself.
