Personally, I think if science degrees are going to have their tuition fees changed, then they should be lowered and the govt should put more money into it.
Plus, if the tuition fees for science are lowered, more people might be inclined to apply, which hopefully will bring more women into science and then all the silly arguments about women being discouraged from science can stop.
Nobody is stopping them from applying. If anything, it's that they don't apply in the first place.
