There are a number of BJU (Bob Jones University) conventions coming to the state of Arkansas. You can read more about them in this article.

I'm not advocating that you use a different curriculum, after all, we think Time4Learning is great. However, if you are looking for some high school courses, BJU might have some information for you.

In addition to this I would like to mention that Let's Homeschool High School is a super site, with curriculum lists and great information all around for homeschooling high school. Check them out!
