[@ShwiggityShwah] Well you're going in a few different directions here so let me try and work it out.

Runes, wards, sigils, and seals are all sort of generalized magical knowledge. They're your sorcerous equivalents of GenEds. You mention "divine forces," and I would lean away from that for now. The nature/existence of gods is a very hotly debated subject among Sorcerers, and the nature of aetheric consciousnesses further complicates the matter.

Medicine would probably fall under Biomancy, though transmutation could be a subset of of Telekinesis. Again, be aware that your characters are basically high school graduates, not really qualified to practice medicine right off the bad, and as far as their professions go, they're Sorcerers first.

Creating a golem would be a complicated subject. If you're just trying to make some kind of automata, Technomancy is probably up your alley. If you're trying to infuse living essence into something, you're probably veering into Demonology (remember those aetheric consciousnesses I mentioned earlier?) which is a restricted discipline.
