> I know I couldn't educate my kids to university enrollment standard other than in physics, maths and such.

Why not? And why would you have to?

I got my kids an English tutor and an Arts tutor once a week to help where I couldn’t.

College students are always looking for work so it didn’t cost a lot.

These days the amount of subject material on YouTube would allow your kids to self learn most subjects once they have the maturity required.

For example for drawing look at what self-taught artists are putting out with just an entry level Wacom tablet.

The exceptions would probably be language (speaking) and topics like carpentry which are very practical.
