Do you have one assignment and two marks?

For what i understand, if your first test was worth 40 points and you got 67% it means you got 26.8/40 (67x40/100)

for the second one which is worth 60 points, you got 73% it means that you got 43.8/40 (73x60/100)

so your overall mark is 26.8+43.8=70.6

this mark is on 100 so you have 70.6% as an overall mark

hope i've helped a little bit

how do I calculate the overall mark?

$\displaystyle \begin{array}{ccccc}40\% \times 67 & = &0.40(67) & = & 26.8 \\ 60\% \times 73 & = & 0.60(73) & = & 43.8 \\ \hline & & \text{Total} & & 70.6\end{array}$
