Depending on how much you can practise each day and how often a week, it will vary from person to person.

Personally, with one hour of practice each day, I calculate with a whole week for a chapter of each course.

[br]Certainly, Fundamentals 1, consists of a theory block (i.e. Chapter 1) that can be simply learnt during the course of an afternoon. But as far as chords are concerned, unless you have prior knowledge, give yourself a week time to practice this very concept until you can play it without thinking about it.
