I tired to answer the same question a long time ago.  Here was the reply

It's actually better to start with the modules, specifically apps/ and
funcs/, and branch into the core only when you need to understand
specifically what each app or func is doing.  This is far easier than
trying to understand the entire core, which is rather complex and
multifaceted, all at once.

This is the way that I learned, and I would recommend the same path to
anybody who might like to become a community developer someday.

Also, stay away from the bigger and more complex apps, such as Dial,
Voicemail, Meetme, and Queue, at least until you have a good
understanding of some of the smaller applications and functions.

In terms of overall complexity, the next step would be formats, codecs,
res, pbx_* functionality, some of the smaller channels (stay away from
IAX2, Zap, and SIP), and possibly even some of the core code, such as
manager.c.
