Everything in this program is scalable and using the 6 pillars of chord-piano, we'll deconstruct and then build everything we do back up, gradually growing in level of difficulty.
You can "stop" (stick to) the level that's challenging, but not too difficult for you, which -whatever level that might be for you- will get you sounding very close to original records you listen to.
The nice thing about a streaming edition like this version of the course, is that you can then redo the course later, going up to the next level.
Everything you'll need to know is available - either in the BootCamp itself, or in the BluePrint.
Everything you already know is easy to skip, or adapt to make it suitable for a level more advanced.
