Strategies to retaining textbook information?

in Off-Topic
This is a pretty noob question but I am hoping to optimize my time studying.. In general my go to for learning is educational videos but I want to be able to utilize books more though. Would this strategy look ok?
1) Read cover to cover copy pasting selected segments/key ideas into your notes to review later
2) Make flashcards out of the notes
3) Go through the flashcards once in the morning and once at night for x amount of weeks (hoping for long term memory)
4) Recite the information from the flashcards into your own words for x amount of weeks (to get comfortable speaking about it in person w/ others. (personal goal))
5) Rinse and Repeat
Any advice is appreciated as I have started to study for the CCIE written which is a lot of text!

I’m thinking about just typing my notes directly into a flash card app(Anki) in the form of questions, so I don’t have to retype them. I think hand-writing them and typing them up does help me, but I’m trying to experiment and see if just typing my notes as flashcards and reviewing is as effective as my previous study habits.
I read an article some where that had some graphs and the basic gist of it was that the more times you review something in the weeks after you first learn it, the more information you retain over a longer period of time.
I’ve seen a different graph that said the best way to learn something is to teach someone else. The second best way to learn something is to actually do it.
