why this course exists & how to use it

This track explains why the course exists and how you should move through it. It is for anyone who is new to the material and wants a clear picture of the tracks, difficulty tiers, and chapter structure before diving in. After completing this short introduction you will be able to state the purpose of the overall course, identify who the intended learners are, and describe how each chapter is built and where specific topics are located. You will also know how to choose a track that matches your current skill level and how to navigate between tracks without getting lost. Start with the opening chapter “Why? Who? What?” before you begin Lesson 1. Read it in full, then follow the recommended order of the subsequent tracks as they are presented on the site. If you are pressed for time, you can skim the detailed explanations of difficulty tiers after you have a basic grasp of the course layout, but do not skip the “Why? Who? What?” chapter because it contains the essential context needed to use the rest of the material effectively.
