4th step indeed is essential. You've got about 9 months til the exam, I think you can squeeze in that extra step.

If you have to cut out a step it would be watching all the videos IMO. I have the videos but barely ever use them as I can probably read through the material twice in the time that it takes for a video to complete. However, if you have the time, I can see them being useful before reading.
