You're probably touting this idea in the wrong place, I've noticed that TSR is full of maths and science oriented people. In a way, I do agree with the points you have made, but I feel that the subjects are so different, you can't class them in the same way, if you know what I mean. For example, I'm not carrying on maths or science above GCSE, as all I did was memorise the revision guide. At the moment I know what a plasmolysed cell is but in six months, I'll have no idea. However I'll always know how to write a good essay, it's always come naturally, just as maths and science come naturally to some.
