Educational Resources
Introduction
In a world where there are paywalls and subscriptions at every turn these are free platforms, courses, and open-education resources (OER) I recommend for learning! It is paramount that we not only attempt to use and adopt open-source alternatives but to encourage others to use them too. As I find and vett more websites or I get recommendations I'll make sure to update this list.
