Study for nicet level 2

I recently passed my level one for systems and I’m studying for level 2 right now, IBC seems to be such a big issue for me when it comes to using the index or using the chapters section of the book. Is there any tips or tricks to get a better hang of it? For NFPA 72,70 I know it like the back of my hand but for instance if the question was what material shall be used for a type IV interior wall finish I wouldn’t know where to even check.
