Absorption costing

Hi - this doesnt seem like a CIMA P1 question so Im not really able to answer because its beyond the scope of my area. CIMA wouldnt ask you to prepare a marginal costing statement in an objective test exam. Also there is no need to revisit calculations such as weighted average cost or Lifo FiFo in this syllabus. Are you sure this was a P1 cima question? If so can you tell me the source? Many Thanks
