Hi,
From what I've seen from the *mock tests* I've finished, it really helps to be familiar with the subcomponents of ITTO's, since the devil is in the details and I'd often find that despite knowing the gist of a TnT, I'd overlook a crucial element that would flip my understanding of how it applies in a situation.
While I've yet to take the exam (currently scheduled on Aug 8/tomorrow), I figured I'll share some of the files I made while studying on my own.
If it's allowed, I've attached an excel file that lists all the ITTO from PMBOK 6 grouped per process. As it's color coded, It might help finding patterns and commonalities between ITTO of each process.
edit: I've also attached it as a png image instead, in case the excel file proves problematic.
Hope it proves helpful to anyone.
