Unless you're going to be a researcher there isn't much need to know it. Even NASA uses the Newtonian equations.

I do wonder, though, what one would be studying in post-graduate physics other than things at either the quantum or relativistic scales? Of course, I don’t really know what the active areas of research are in the physics faculties of the world. And there’s a lot of crossover between physics and chemistry in the quantum/particle physics area.
