First idea: I have a #mathpix licence. So I could PDF all my solutions and convert it to #LaTeX (preferred over Word).

Then, #LaTeX packages like #xsim or #exercise coude comme to the rescue. But beyond all the syntax questions that will come with any package I'll use, I'm unclear on how to organise and store those exercises and solutions.

In #tex files, in a database?

Feedback and experiences would be most useful 🙏🏼
