Has anyone done this course? What did you think? was it worth doing? How much time did it take in terms of day to day extra work? I am in a school that has recently come out of special measures and maths was high lighted as an area of weakness. it has been suggested that i do this course which i am more than happy to do as long as i don't end up with no free time at all. any ideas / comments welcome - as long as they're not rude!
