For me, the Ninja Notes were a supplement to FAR. When all the craziness of FAR seems overwhelming – you can go to the notes to get a nice baseline of what's important, the basics of that section and then go attack the mmaterials.
I would highly recommend a book in conjunction. I've not used Ninja Book. The Becker book was sufficient but not perfect.
Notes to get a high level overview, book to get details, MCQ until your eyes bleed and then notes again to keep it all together is a pretty good combo.
I also recommend in advance:
* Look at the actual FASB conceptual statements – that comprises much of the authoritative source
* Get financials for a) your favorite big charity, b) your favorite public company and c) your favorite local government like a city. Review the financials. If you can understand these you are better off than Becker or anyone else telling you what's in there.
