You mean based on #819532?

No, I don't. I have a child in (public) secondary school now. I'm helping with math homework and test preparation.

It has been harder than I initially imagined, and sometimes frustrating, because of how different they teach math now compared to my own childhood. Instead of mastering one thing at a time, then building on top of that with the next, now they always do multiple new things at the same time, then re-iterating over topics later (trusting it will eventually sink in). Sometimes it's tricky for me to even understand the tasks, due to new language invented.
