3lilaggies,
Back in the dark years, when I was a fresh engineering graduate just starting out working with the ASME B&PV codes, they also seemed somewhat difficult to grasp. 20 years hasn't changed that much ( hehe :0)).
The above posts make a lot of sense. Don't expect to grasp them all at once as it won't happen. My advice to those just starting to work with the codes is to first learn where to find things. Get an idea of the larger topics and then delve into the details. Above all, don't be afraid to ask questions. It's been my experience to occasionally find things where you wouldn't expect to. This site is an excellent resource, lot's of sharp individuals with an amazing range of experience and knowledge.
Regards,
RLS
