Very informative, and just the right speed. I like this dude's work. Thank you for taking the time to make resources like these. I am attempting to join the Canadian Armed Forces, and the trades I can see myself in all require advanced high school mathematics. As I only recently obtained a GED (after dropping out of high school four or five years prior to that) I can safely state with authority that I do not possess said skills. These videos at least give me a chance to brush up on the really hard aspects before I have my aptitude testing. In short, thanks.
