I did the morning one and got the same questions as you (recruitment companies etc.) thought the first q in section c was fab (the shutdown decision). I had no clue re environmental accounting as took the chance on skipping that chapter. Ran out of time for the last one. Found Sections A and B easy enough – annoyingly no limiting factor, relevant costing, or variance analysis questions. By the looks of the answers, seems I may have got the easier C section questions!
