PMHelp how to do my revision

In future you must ask in the Ask the Tutor Forum if you want me to answer. This forum is for students to help each other. To revise, you must work through every question in your Revision Kit, attempting questions before looking at the answers, and learning from your mistakes. It is also essential that you attempt the mock exams in the Kit under exam conditions (especially with regard to the time limit) and that you practice the CBE exams on the ACCA website to ensure that you are happy using the spreadsheet and word processor provided. Questions in Sections A and B of the exam can come from any area of the syllabus. Questions in Section C "will come from the decision-making techniques, budgeting and control and/or performance measurement and control areas of the syllabus. These questions may also include requirements related to the information systems area of the syllabus."

In chapter cvp ,when calculating c/s ratio , in case the question asked to calculate in terms of value not per unit , should we take ( contribution per unit x budgeted units ) / (selling price per unit x budgeted units)

In future, if you want me to answer you must ask in the Ask the Tutor Forum. This forum is for students to help each other :-) In answer to this question, it makes no difference - the CS ratio will be the same whether you do it per unit or you do it over the total units (try it yourself and see what I mean :-) ). Usually we do the calculation on a per unit basis, but it depends on the information given and which is therefore faster. But the answer will be the same anyway because it is a ratio.
