As you can see in the classroom the courses are locked, all you have to do is press on any course and pick 1 of 2 memberships. The first membership called “standard tier” is a 10$ month-month fee.
The second membership called “premium tier” is a 100$ annual fee, which saves you 17%.
Both memberships allow access to the same videos. So don’t worry about the difference, it’s just a way to help you save some money. Once you’ve joined a membership all videos will be unlocked, for you to learn and progress!
