@boomerang,
I don't have time right now to listen to the whole thing, but I have never understood why we had to take geometry, which I hated and is as far as I went in math. I was an A student in algebra, but again, don't really know why we had to take it.
I also have never used the electricity component of science.
I think more applied skills would be more useful to the general population. If you need the information for something, you could always ask someone who knows.
