Marking

Hello, Dear Tutor
Hope you are fine.

I have one question: assuming that I am calculating “Cost of sales”, and the allocated mark to cost of sales is 4. I have produced my workings, I have dealt with several items, which are correct, but the final figure is incorrect due to only one item being either omitted or miscalculated. So, that means, I will lose the whole mark because of that little mistake although I did well with the other items, showing accurate calculation.

Thank you so much
