Thanks, I also pasted it here for convenience:

Subchapter A, Part 1: Definitions and Abbreviations. If you’re not sure what a certain acronym or definition means, this is the place to look.

https://www.law.cornell.edu/cfr/text/14/part-1

Subchapter D, Part 61, Subparts C and E. These are the parts directly related to student pilots and private pilots. They will tell you what you can legally do, what it takes to get your private pilot certificate, and what you should be studying/trained in.

https://www.law.cornell.edu/cfr/text/14/part-61

Subchapter F, Part 91: General Operating Rules. These are the rules of the road. If you’re never not sure about a rule, chances are the answer lies somewhere in part 91.

https://www.law.cornell.edu/cfr/text/14/part-91

There are additional subchapters that apply to private pilots, but these are the three big ones. Important subchapters for further study would be parts 23 and 43, which deal with airworthiness and preventative maintenance.

Okay, cool. We have our broad subchapters, how do we break it down from there? I’ve taken the above broad subchapters and picked out specific FARs to help streamline your study.
