    If you choose to complete the calculations using Excel, you must only use the formulas exactly as they are provided on the lecture slides.

    Please note that Excel contains many built-in formula functions that may produce slightly different answers due to rounding or calculation methods. For the purpose of this assessment, we will only accept answers that are obtained using the formulas provided on the slides.

    Markers will not apply a range of acceptable answers. Therefore, if you use Excel functions or formulas that differ from those shown on the slides and your answer varies even slightly from the expected result, no marks will be awarded for that question.

Make sure you pay extra attention to the instructions given to each question in this paper.

Write then submit before the indicated time expires or before the time is up from when the invigilator started to time the session.
