Any advice for those studying on how much focus the exam might be on 2016 CBC?
The latest code cycle I have professional experience is 2013.

I am flipping through the ICC book running through the significant changes to CBC and at first glance Table 503 which I finally feel like i know In and out after doing several projects in 2013 has been completely re-written and split up into various tables in the 2016 CBC. It's nearly the same information but reformatted... but just one more thing to re-learn in a short amount of time.

Any thoughts appreciated!

My understanding is that the big CBC updates between 2013 and 2016 were in CALGreen and Energy code. IMO those are the main ones to review anyway. As I recall, my test was pretty light on code.

Good luck!
