He won't need to be tested on the fundamentals of instruction. He should pay attention to anything pertaining to the category sought, if adding a category; AIR for airplane, and all, which means applicable to all.
A very good practice is to shoot for something a bit higher than the bare minimum.
I went the other route; adding a CFI-G to a normy CFI cert.
The test was short, maybe like 15 questions. It was mostly glider related but there were some instrument questions about NDBs of all things! This was in 2016.
There is more study material on the market for powered flight certificates and its so much easier to come by. The thought that this guy seems to be taking more time and energy finding shortcuts than just doing it the right way is disrespectful to the craft.
