Answer 1

On Wordpress, it's fairly easy to implement.
There are ready-made themes, plugins that support remote learning (access to a certain part of the content). Look at the query "Wordpress LMS".
There are also free ones, review edu-biz.org/2018/01/10/online-shkola-wordpress
Or another general purpose CMS like October CMS.
If you need a simple system, then it’s easier to build your own than to customize some ready-made solutions.
