Dear Customer,
1. In the menu on the left, you can find a huge documentation. Each component with a label "Premium component" is available only in Pro version.
Search through the documentation and you will find hundreds of your premium components, plugins and thousands of available combinations and variations.
Here is an example:
https://mdbootstrap.com/sections/e-commerce-sections/
2. Here you can find your premium tutorials:
https://mdbootstrap.com/admin-dashboard-tutorial-bootstrap-4-material-design/
But I strongly recommend you to start with the free one, because they cover most basic concepts:
