I think you've outlined your problem when you said:
Im currently using the Aviation Theory Center Aeroplane performance,planning and loadingn for the ATPL. It is referencing 737 performance charts. I thought we would be tested on the 727 p charts in the blue 727 handbook?
Get the info from Nathan Higgins at AFT! Esp. if you're self-studying
I self-studied 5 of the 7 ATPL subjects, and found that Nathans notes were in a league of their own. Trevor Thom and Aviation Theory Center notes were nowhere near as good.
DIVOSH!
