CKA Course: Multiple Schedulers

Why is the lesson “Multiple Schedulers” even included under the section “Scheduling” when it uses the advance concepts that have not been taught yet. The Lab just destroys all the motivation where what is being done is not understood at all. Even the Course Instructor is just running through the topic without explanation.
Please have a proper layout and explanation and dont include such topic in middle which can kill the motivation of learners.

The topic is here to make sure that you understand how pods are scheduled to nodes, and how you can modify this; it’s an application of concepts we’ve been building up in this section of the course. It’s something that you might need to do in a production environment when you have unusual work loads that won’t run on a generic node, but has special requirements. Look at it as an opportunity to “apply what you’ve learned”. The lab is a bit more difficult than usual, to be sure.
