Just found out that Hillsdale College has FREE ONLINE COURSES in things like: Constitution 101 (The Meaning and History of the Constitution) & Economics 101.
Check out their website HERE.
I vaguely remember learning about the Constitution as a child through school-- so this will be a great course to take to freshen my memory.
Hillsdale College will continue to offer free online courses. They will vary from time to time. So keep looking back to see what's offered next.
