Overlooking the alphabet-soup for a moment, is "physical science" an odd name for Physics, or does it mean something else?
If Physics, are you saying Physics is taught to a far lower level of difficulty than Biology?
BTW, I do see the irony in using the internet to say these people think Physics is not "real science" ! :-)
While turning to the many-letters-plus, why would the complainants link their sexual orientation to their academic ability? There is no such link in reality, so their complaints mystify me.
(I have just come from a PM conversation here with an American resident who explained to me that US schools teach maths in a curiously fractured way, to quite low levels. Consequently students advancing to higher education think some important topics including calculus are only for exceptionally bright ones. He studied electricity and electronics, which are of course highly mathematical, at college, but I don't know to what depth.)
