6/7, but for example with no knowledge of the french language i could only tell 'maillon fable' was 'weakest link' because i use maillons as connecters in caving. without that little bit of nonsense experience i would have looked like a ignoramus. sometimes knowledge comes to you in roundabout ways.
also, especially with classical music, i cant help feel that some of these things are general knowledge for a specific group of people, in a period of time that has passed. much the same feeling that i get with university challenge. i can answer a fair few questions but i dont feel that i have learnt the answers in the way they think i should have. its basically just accumulated reading and tv watching in my own time rather than a very specific type of education.
