I just received P90X3 today and am excited to start it! There are worksheets that you can download and there’s also a fit test which you should do before you get started. Here are the links for those:

P90X3 worksheets

There’s also four schedules or four different calendars you can follow tailored to get different results.
CLASSIC is what the test group did – basic schedule to get RESULTS in every way.
LEAN if you want to just Lean out  (really great for ladies who do not want to “bulk” up or “get ripped”.
MASS schedule if you’re looking to put on muscle.
DOUBLES for those who have time for an hour workout or want to get their desired goal twice as fast!
Something for EVERYONE!
