Formula in spreadsheet

Also is using the below formula in spread sheet fine? Deff tax credit =-(6000-(14000*0.3))

Hi, You need to be careful using the formula in the spreadsheet as if it gives the incorrect number then you will not gain any credit. You still need to show your working to score credit if the final answer is incorrect. Have a look at the recorded video that was put up over the weekend that answers a CBE question using the spreadsheet given in the exam. Thanks
