for schizophrenia (only option we share )
i think an 8 marker on token econmy and a 16 marker compare and discuss. drug therapy vs CBTp and family therapy i could also see a 8 marker discuss/apply for psychological explanations from a stem paragraph.
As each option has 24 total marks so that means at worst an 8 and 16 marker per option, but they can also have 2,2,4,16 mark questions in that order in a section. they could have the essays be on any topic in the advance info so best be prepared for all of them i think.
