Are A2 psychology questions ever repeated?

Im not sure 100% so dont point the gun at me if im wrong! but because a lot of students will be retaking the 2015 exam and the 2015 exam is also used as mocks. Im pretty sure they wont use the exact same question. Throughout previous years there has never been a repeat in exam questions so i don't see why they would do it. Anyway , I wouldn't say don't revise institutional aggression because you never know! However i am avoiding topics that came up last year.... for example:

Eating - Social Psychological explanations of Anorexia (but revise biological!!) and Dieting success and failure.
Aggression- Institutional aggression
Sleep- Evolutionary explanations of sleep and narcolepsy

Good Luck
