Hello,
I created a table where I display my university grades to calculate my average. However, some grades are worth more than others.
For example, in American Civilization, the first test was worth 30% of the final grade and the second test is worth 70%.
In the first test, I got 8.5/20 and in the second, I got 17/20.
What formula should I apply to get the average of these two grades based on the different percentages assigned to them?
Thank you for your help!

Good evening colinep,
Assuming the grades are in the range B2:C2 and the weights (either as percentages or simply 3 and 7) in B3:C3, in the cell where you want the average you put the formula:
=SUMPRODUCT((B2:C2)*(B3:C3))/SUM(B3:C3)
Best regards
