I've used both the live and recorded classes. Their live classes are more inexpensive than other online schools, but it's still more money than I like to spend. So, we haven't done a lot live. We did Latin since it's a hard subject for me personally. And we did writing because of the difficulty of grading on my own. Now that Homeschool Connections has the grading service for the recorded Latin and writing, I may do that instead next year. My kids really like the interaction of the live classes though, so we'll see. I like that you can pick and choose classes and don't have to sign up for a whole program.
The Unlimited Access is a godsend. It's inexpensive and there's a lot to choose from. If you're not Catholic, keep in mind that most of the classes are taught from a Catholic ethos. The writing program (which is excellent, imo) would be fine, but history and literature are going to have a strong Catholic influence. And theology too of course.
The recorded classes are especially good if you have a self-directed learner. If not, make sure you're keeping your children on task. Put it on your planner to follow up. Of course, you'll be doing all the grading unless you pay extra for grading services. Most of the classes come with answer keys. Also, you can do classes as a family if your kids are close together. The kids watch the history classes on the television with my husband.
