Thats one of many benefits. The content itself is still useful. I’ve long since forgotten my highschool advanced maths content, but I know how to think about rate of change and probabilities and normal distributions, etc. My current job is also science based and I often need to explain things to lay service users. It’s remarkable sometimes how far back to basic concepts I need to go to help them understand. Even colleagues who didn’t learn certain aspects of match or physics up to high school struggle more than necessary.

I think even the forgotten material has been benefitting you all along.
