Questions about this tool
Why is the overall percentage different from the average of subject percentages?
Subjects with a bigger maximum weigh more in the total. The overall figure comes from the two totals, not an average of percentages.
Can I mix subjects out of 50 and out of 100?
Yes. Enter the correct maximum for each subject and the tool adds them up.
Can I name the subjects?
Yes. Write the name first, then the two numbers, such as History 47 50.
