I just ordered this weekend. The math topics covers Basic Math - Trig. Note: For example, Geometry has a 2 pack with volume 1 and 2 sold together or individually. If you get the 2-pack, it's considered 1 item. I almost didn't notice this tip. So, you could receive more than 10 free videos!

Go to sdlearn.com and click on "clearance", click on "free vhs."
Type "fr33vhs" at checkout.

Don't procrastinate; Do it now!
