DFS - Definitive Cash Flow Pro-forma

System

We have been given two different cash flow pro-formas. On the reconciliation of cash from operations........ one has adjustments for depreciation, interest, investment income and gain/loss on disposal and the other just has depreciation and gain/loss. I realise that with the investment income it is added one way and taken off another but are we penalised for not including it. Also, obviously the starting profit figure depends on whether or not you include the interest but we have been told one way, then the other and then back to the old way. With only a short time to go before the exams, can anyone give me a clue as to which one the AAT are after?? At this rate I shall be using half of each!!
