What Grade Do I Need on My Final Exam? Formula and Examples

If you not study in start and before one week of exams you starting the studing then you not need a guess. You need the exam score that generate your course score that you want to achieve. By this article we tell that how to calculate a number by hand as manually and then check with our final grade calculator tool.

Open the Final Grade Calculator Enter current grade, target grade, and exam weight. See the score you need plus a what-if table.

TO check that which score you needed for your final exam

Here are below things you need first to calculate it:

  • Current grade – This is your current progress in percentage fore the finals. Don’t use your LMS portal total as because they uses the ungraded exam as a zero.
  • Target grade – This is the result that you want to achieve for after exam. That’s your goal. Normally you want 90 for an A while if you not fast in learning then your target will be 70 to pass your course.
  • Final exam weight – That means that how much exam is worth like in 40/40/20 formula there the 20% is of your final grade that mean’s that your exam weight is 30.

Do not use your last test score as consider for current score. You should always use the current course average that you can get from your portal. But remember that if portal already count the exam as zero then you not get the accurate result then you need to manually calculate the current progress and then use our calculator.

The formula

Required final exam grade =
(Target – Current x (1 – Final weight)) / Final weight

Write the weight as a decimal. A 25% exam is 0.25. The piece (1 – weight) is everything in the class that is already graded.

Example 1: Protect an A-

Current grade 88%. You want 90%. Final is worth 30%.

  1. 1 – 0.30 = 0.70 of the course is done.
  2. 88 x 0.70 = 61.6 points already in the bank.
  3. 90 – 61.6 = 28.4 points still needed.
  4. 28.4 / 0.30 = 94.7% on the exam.

A high A on the exam gets you there. A 90 on the exam would finish around 88.6% – still an A- on some scales, a B+ on others. Always match the letter cutoff your school actually uses.

Example 2: Can I still pass?

Current grade 58%. You need 60% to pass. Final is worth 20%.

  1. 1 – 0.20 = 0.80 already done.
  2. 58 x 0.80 = 46.4.
  3. 60 – 46.4 = 13.6.
  4. 13.6 / 0.20 = 68% on the test.

A modest test score is enough. That is the point of calculating before you panic: a passing calculator often shows you do not need a miracle, you need a plan.

Example 3: The required score is over 100%

Current grade 72%. You want 90%. Final is worth 15%.

Required = (90 – 72 x 0.85) / 0.15 = (90 – 61.2) / 0.15 = 192%.

That A is not available from the test alone. You should down the target to 80% and recheck the calculation: (80 – 61.2) / 0.15 = 125% – still impossible. At 75%: (75 – 61.2) / 0.15 = 92%. A strong test can still lift a C into a C+, but it cannot manufacture a large share of the course that has already been graded.

If your scores goes up to your target?

One “need 97%” number is useful. A table is more useful. For a current average of 85% and a 40% weight, overall grades look like this:

If you score on the testOverall course grade
50%71.0%
70%79.0%
80%83.0%
90%87.0%
100%91.0%

You can see that an 80 keeps a B, and only a near-perfect exam reaches 90. Use the Overall Grade and Need on Final tabs on the grade calculator to build this table for your own numbers.

When it count as test

Some instructors put the final exam in same category as a unit test. If they do like then exam is not separate. Then it’s mean that 40/40/20 that formula format is not apply.

E.g if the tests are 50% of the course and you given the four tests already. then the fifth last one is consider for as final and as because it is 1/5 ratio so we can say final is 10% of the course. For the good result then treat the 4 test that already given take the average of them and consider them as final as another test of equal weight. And then combine with homeowrk category and everything else on the weight tab formula.

Grades instead of percents

If your LMS system show grades instead of percent. Then get the midpoint percentage e.g(B = 84.5, A- = 91, and so on) And also you can use and see our grade percentage table at the calculator page. check it out. When you get your percentage then from that that you can convert it back to the grade with our final grade calculator. This gives you a clear idea of what grade you need to achieve on the exam.

FInal grade calculator help in studing

How this calculator it help you during study let me explain. As it not upgrade your class grades it will help you that on which class you need to give more time compared to others. e.g If the first class needs 74% on the final, while the second class needs 96%, then the second class should get more hours. If both required equal scores like below 80% then you can treat both ones as normal and you can do your sleep in normal. This is the real work that our final exam grade calculator solve your problem that turn your anxiety into a study order.

And if your class use the category format system instead of perentage then checkout our weighted vs point-based grading article. And if you are studing in school and your results provide by quarter bases then checkout our quarter and semester guide article.

Frequently asked questions

What is the final exam formula to calculate grade?

Your Required final exam grade = (Target – Current x (1 – Final weight)) / Final weight. Always write the weight in decimal. e.g A 30% final is 0.30. The (1 – weight) piece is everything in the class that is already graded.

What if I need more than 100% on the final?

That target above 100% ofcourse it’s not possible. From that to make it possible either you need to downgrade your target level of your grade that you want. And other option of extra credit. Remember that a small final weight it can’t fullfil such big gap in the remaining course.

If final counted as test instead of its own category?

In that scenario then we not considered it from separte 20 or 30 percent as because it change the test average. Average of existing tests, treat the final as another test of equal weight, then combine with homework and other categories on the Weighted tab.

Should I enter letter grades or percentages into the final grade calculator?

That’s depend on the thing which available. If your LMS or your teacher give you the percentage then percentage use it. And if your portal give you grade mean letters then with our table that is at the calculator page get the mid percentage or use the letter dropdowns on the calculator that it auto pick the mid value. Also remember that different schools use different cutoff values so consider letters as a translation.
