This proposal aims to add a new Skills construct at a global level that would replace the existing refresher explorations method that is employed for specific answer groups in questions. Along with this, pretests can also be added to explorations testing particular skills. For this, a skill editor is created for skill creation. The questions for the skills will be from the common Questions construct in the back end. In the future, collections are to be removed and replaced by topics and stories, and hence this project lays the foundation for that also by creating a topic and story editor (and the backend constructs for the same) as well as integrating skills with those.
