for the last qestion my teacher who marked papers said that 2 driviing ad 1 restraining forces were required plus an appropriate link with an org example to get 6 marks. the other 4 marks include definition of driv/rest forces, defination of org change, mention of how driv/rest forces effect change, and a statement on how driv/rest forces affected change at the exemplified org mentioned.
On another note, my teacher also said of the 400 papers she marked, only 2 scored 60 or above. A large proportion of results were between 25-40. If we take this sample as a consensus for the rest of the students, could you almost say that getting 60+ would get you a 50 (with a top SAC result as well)
