"but with all due respect, i always found the 'art' which is taught in secondary schools is largely of the copy life, form, shape, light etc variety. Rather then what you learn later on at university about expression and what art is, can be, where it comes from inside a person and what it means to create it."
I did do a fine art degree, you know- they don't let you teach with just a GCSE 
Look at the life rooms in the Royal Academy, The Slade, and City and Guilds, for example. I'm sure they would be delighted to be told that they are not part of the 'grown up art world'
. Measuring, light, form, shape etc. is taught- I find it odd that you would cite such things as precursors to 'expression', and presume they are only taught in schools. When painting the human form, it is necessary to study the human form, at any level. Picasso was able to abstract the human form so well, as he knew where everything was supposed to be; observational drawing/painting is just one facet of art, not a rung on a ladder leading to 'expression' or 'coming from inside'. I find those terms a little trite, TBH.
Conversely, GCSE syllabi require very little in the way of observational drawing, and require much more 'expression', contextual understanding and personalisation. In other words, it is very different from when we were at school (assuming we are about the same age?) and, far from being the end product only reached at university level, is many secondary students' first experience of art education. Formal life drawing and painting is rarely taught in schools.
BTW- pretty watercolours of boats are massive in Hackney right now
