Basically I wasn't taught mathematics very well in High School as I kept getting the same teacher that didn't turn up much.
It never bothered me at the time but the rest of the world seems to find it an important tool and there are significant gaps in my knowledge (as I soon realised studying Physics).
Long story short, here is a good place to test yourself out or improve on lack of sufficient knowledge. Completely free, discovered it from a TED video.
