66.4% overall, 32 marks needed (80%)
The average of the two percentages is 66%.
About Test Score Percentage Calculator
A test score percentage calculator turns marks into a percentage. Divide the marks you got by the total marks and multiply by 100: 42 out of 60 is 70%. When there are several tests there are two sensible ways to combine them. Adding all the marks and dividing by all the total marks means a long test counts for more. Averaging the percentages makes every test count equally. Both are shown.
To plan ahead, enter a target overall percentage and the total marks on the next test. The tool works out how many marks you need on it, given everything you have scored so far, and tells you if the target is out of reach. For a course with weighted components, such as coursework and an exam, use the grade calculator, which handles weights.

Frequently asked questions
How do I calculate a percentage of marks?
Divide your marks by the total and multiply by 100. 31 out of 50 is 0.62, or 62%.
What is the difference between the two averages?
The overall percentage adds all the marks together. 73 out of 110 is 66.4%. The average of the percentages (70% and 62%) is 66%. They differ when tests have different totals.
How many marks do I need on the next test?
Multiply the target by the combined total including the next test, and take off the marks you have. For 70% after 73 out of 110 and a 40 mark test, you need 0.7 times 150 minus 73, which is 32 marks.
What if the target is too high?
If the marks needed are more than the test is worth, the target cannot be reached on that test. The tool says so, and you can try a lower target or a longer test.
Can I turn a percentage into a grade?
Not with this tool, because boundaries differ for each paper and exam board. Ask your teacher for the grade boundaries.
