My daughter finished the first level paces and is working her way through the ACE second level paces. As with the Bible reading paces, there is a big difference between these and the other subjects at the same level. Animal Science and Bible reading both have a lot of big vocabulary words and lots of reading along with fill in the blank answers that in other subjects would be multiple choice. If your child is a second grader and zooming through her paces, this may be a good fit for extra learning but probably not for most students who just finished paces 1001-1012.
