J.D system for professors/academics?

I’d been grappling with this as I set up my JD.

I’m not currently studying, so this is manly backfilling my existing material, but I went for this structure.

Say for my undergrad degree HPCP at University of Adelaide. I created an ID each for these to contain info relating to the university as a whole, and degree specific things.

Then each actual course gets an ID, such as Maths 101.

So for an Australian 3 year degree, you should use up 26 IDs. Plenty of room for multiple degrees at each level + repeat courses + change of degree/universities + clubs etc.
