Hello, I'm new here. Is there a recommendation on the videos to following each day/week/month, checkpoints, or another type of schedule to use as reference? 

Thank you. 

Hi, Scarlett! We recommend following the level 1 beginner course followed by level 2, and then exploring the site at your own pace. One lesson per day is recommended! Please see more advice below:
