Every lesson in the Fundamentals Courses should be considered a "when you can do what I am doing" lesson. You have not accomplished it until you can do the skill presented or understand the idea presented.

This doesn't mean you can't move forward in the course. :) As long as you make time to go back and continue working on the previous lessons until you have mastered them.

When you can do them clearly, cleanly, consistently and competently.

I discuss this here in my instructor forum:

Short answer: it takes as long as it takes and every individual is different.

I think some lessons seem easy and require only "understanding" (like how chords are related to scales) while others such as chord changes I find very difficult to do even after months of trying. Should I stop at the chord changing ones and do nothing but that until I can change from chord to chord flawlessly? Or do I practice changing from chord to chord every day while I am watching other "theory" videos?

Good question. It depends upon your goals, how much time you have to dedicate to practicing and how much skill you bring to the task (absolute beginner, intermediate, etc.).

Also, notice that even though something is "only an idea you have to understand" it is also tied to some physical skill you must apply.

Am I supposed to be memorizing the three letters of the scale that we are using to go to the next chord? Is this a recurring thing in guitar or are they just practice excersizes to be able to switch from simple notes to chords and back.

You should be able to do the skill and understand the idea. And yes, that is something that is crucial to playing the guitar!

Hope this helps. Let us know how it goes. Happy learning and playing.
