She Gets Me is for intermediate-level speakers, and you need to have at minimum, an intermediate listening level to understand the videos.
The Opal Library is designed for you to focus on what your gaps are.
For example, maybe you want to target grammar points that may be difficult for you conversationally. You are free to pick and choose which topics you want to watch, and also suggest new ones.
Or maybe, you want to review your basic grammar to develop a solid foundation. These videos can be excellent reminders to refine your basic skills, and fill in any gaps that you may have.
Self-study of these videos and active engagement with the content can really help you improve your listening and speaking.
