Common questions

What is the difference between a points grade and a weighted grade?

A points grade adds every point earned and divides by every point possible, so a big assignment counts more simply because it is worth more points. A weighted grade averages category percentages by the share of the final grade each category is worth, so a category counts exactly as much as the syllabus says regardless of its size. They are genuinely different numbers. A 10-point quiz scored 10 out of 10 with a 200-point exam scored 160 out of 200 is 170 out of 210, which is 80.95% and a B-. The same two scores weighted at half each are 90.00% and an A-. Use the mode your syllabus describes, and if it says a percentage next to each category, that is the weighted mode.

How do I work out my grade if the lowest score is dropped?

Remove that row, because this calculator never drops one for you. Take a term of 178 of 200, 88 of 100, 82 of 100, 145 of 150 and a pop quiz of 2 of 20: that is 495 of 570, or 86.84%, a B. Remove the pop quiz with the Remove button beside it and the total becomes 493 of 550, which is 89.64% and a B+. Doing it by hand is deliberate, because which score is dropped, and whether the policy exists at all, is a syllabus question this page cannot see.

How do I set a plus and minus scale?

The Scale control has two settings. Plus / minus is the common A+ to F scale with A+ at 97, A at 93, A- at 90, B+ at 87 and so on down to D- at 60. Whole letter drops the plus and the minus, so A starts at 90, B at 80, C at 70 and D at 60. The full band table sits under the calculator and redraws when you switch, so the letter you are shown can always be checked against the numbers it came from. If your course uses bands that are not on either scale, read the percentage instead of the letter: the percentage can be checked against your own grading bands.

Is anything I enter uploaded?

No. The arithmetic runs in the page, in your browser, and no assignment name, score or total leaves the device. Your rows, your categories, the percentage box and your scale choice are kept in this browser's own storage so the tool is still filled in when you come back, and that copy never travels either. Clearing your browser data clears it. There is no account and no sign-in.

What percentage is an A?

On the plus/minus scale here, 93% up to 97% is an A, 90% up to 93% is an A-, and 97% and above is an A+. On the whole-letter scale, 90% and above is an A with no minus. Those are common United States conventions rather than a rule, which is why the table is on the page and the scale is a control rather than an assumption. A school that puts an A at 94, or that uses a 7-point scale, is not doing anything unusual.

Does 89.5% round up to an A minus?

Not here. A band includes its own floor and runs up to the next one, so 89.99% is a B+ and 90% is an A-. Nothing is rounded on the way to a letter, because rounding is a rule that belongs to a syllabus and a professor, not to a calculator that has never read either. The percentage itself is shown to two decimals, and the line under it tells you how many more points would reach the next letter: from 493 of 550, two more points make it 495 of 550, 90.00% and an A-.

Do the weights have to add up to 100?

No. Weights are normalised by their own total, so entering a homework category worth 30 and an exam worth 60 gives 83.33% rather than refusing, and the line under the result says the weights add up to 90, not 100, and that each is scaled by 100 ÷ 90. That is what you want mid-term, when only part of the course has been graded: it is the average of what has actually happened so far. A weight of 0 across every category is the one case that has no answer, and it says so.

What grade do I need on my final exam?

Choose Final exam, enter your grade for the work already graded before the final, the course percentage you want, and the final’s percentage weight. With 86% before a final worth 25%, reaching 90% requires (90 − 86 × 0.75) ÷ 0.25 = 102%. That exceeds the assumed 100% exam maximum; even a perfect final produces 89.5%. The tool names unreachable targets and targets already met with a zero instead of treating either as an ordinary exam requirement.

Can I use this as a what-if grade calculator?

Change an assignment score or category percentage to see its effect on the current average. Ungraded rows with both score fields blank are skipped, while an entered zero is counted. Use Final exam for one remaining component with a known weight. This is course-grade arithmetic; GPA needs course letter grades and credit weights in GPA Calculator.

Can I grade a test by the number of questions wrong?

Yes. Easy grader takes a total and the number wrong, then subtracts to get the correct score. Three wrong out of 25 means 22 correct, 88%, and B+ on the displayed plus/minus scale. Half marks work too. The score chart lists wrong, correct, percentage and letter; choose whole-point or half-point increments.

Does this average letter grades or automatically grade essays?

Enter numeric earned/possible points, category percentages or a percentage to read against the displayed letter bands. It does not infer scores from an essay, apply a grading rubric, curve a class distribution, convert international exam scores, or reverse a letter grade into a unique percentage. For course letters and GPA credit hours, use GPA Calculator.

Can teachers use this as a gradebook calculator?

Use Points or Weighted for one student’s course record, entering the scored assignments or categories and their totals or weights. Easy grader handles individual tests from questions wrong, and Quick handles a correct score over its total. Draft inputs are kept in this browser. It does not manage a class roster, read a school portal, synchronize Canvas or PowerSchool, automatically grade essays, or apply a school’s unpublished grading policy.
