Homeschool ping.
We used these for the majority of our high school curriculum. Latin, Algebra 1 and 2, Fundamentals of Math, Photography, Joy of Science, St. Augustine’s Confessions, Understanding the Universe, etc. The Great Courses Plus charges a monthly fee ($20?) but you have access to hundreds of their courses! My kids are conservative enough to catch the liberal leanings of some things but we just use it as a teachable moment to go find alternative reasons/facts/etc. There going to face this in college so an introduction to it in the comforts of home (and my watchful eye!) was a good plan.
Great for homemaking skills, too! All kinds of cooking and gardening classes. Art and music appreciation. You can truly build a good curriculum through them. Lots of science choices! All courses come with work/textbooks.
