If i’m expected to give a return calculation, and I dont know the calculation, but I know the mechanics behind why the rate should go up/down etc, should I write this in the answer or no? What i’m trying to get at here is it worth trying to get part marks? Or is it a zero sum game in the sense that you get 0 or full marks?
Well for rate calculation you have to know how to calculate it… Look to past exam to see how, it’s a inflow/outflow analysis you need to do and go from there. **Always go for part marks.
