Every single year/quarter of a person's basic education includes math and science (physics and then biology and chemistry, then a bit of cs) where I am from. Thus, worst case scenario a person has spent 9 years on that stuff (among other topics sure).
Sure I can see art does not get a lot of focus from what you are saying and I do not have experience in your system to say what the balance kept. But I can see if a school is running under budget and needs to reduce something that art/music is the first to go. Pity.
