The most efficient way to read the CFAI curriculum? test, background, efficient, concepts

homie

For earlier levels I used Schweser notes, but for Level-III decided to read CFAI curriculum. It’s been hardly 2 days reading it, but found there are repetitions of the same concepts many times, they go to historical background of any concept in detail (not sure if the exam would test it) and similar things those are taking more time to move faster. Have been highlighting things that I feel like coming back at the review stage.
Curious about the approach of others to read these books…
