My teacher was pretty strict on marking !
I think you should know some of the definitions word for word (e.g. morbidity,health status indicators ) and when you get to stuff like "Ottawa Charter" and "social model" , you have to have a definition that is close , but doesn't have to word for word.
Yupp!

Whenever you have an "official" definition (like one that's created by WHO, UN, VicHealth, AIHW, etc) try to aim for it to be very close or exact to the real definition - don't go so far as to totally paraphrase it into your own words as assessors usually look to see if it matches the real "official" definition

Official definitions include Health, all the health status indicators, health promotion, human development, sustainability, to name a few

For your sacs though, your teacher may be more or less strict or lenient when it comes to definitions so I guess you could ask them if it has to be word-to-word for sacs
