The result is not an official grade

A number from this calculator is arithmetic performed on numbers you entered. Nothing more.

It is not an official grade. It is not a grade issued, confirmed, predicted or endorsed by any school, college, university, examination board or awarding body. Only your institution issues grades, and only its record counts.

Where a result here differs from your school's number, your school is right. Not as a courtesy — as a matter of fact. Its policy defines your grade; ours defines nothing.

Not a prediction

The final exam mode tells you what score would be arithmetically required to reach a target, under the formula shown on the page. That is a calculation about numbers, not a forecast about you, your exam or your course.

A result of "89.67%" does not mean you will score 89.67%. A result of "106.33%" does not mean you have failed. A result labelled "Target secured" does not mean a school will treat the target as secured — many courses have a separate rule that the final exam must be passed or attended regardless of standing, and no formula can see such a rule.

Why a result can legitimately differ from your gradebook

The calculator knows only what you type. It does not know your course. It cannot see:

Each of those is a rule in a document, not a calculation. Why your calculated grade differs from your gradebook works through the five most common causes with real numbers.

About the default grading scale

The calculator's default scale — A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, F ≥ 0 — is our default, not a standard. There is no single grading scale, and we do not claim one.

Published policies differ at exactly the point that matters. SUNY Broome Community College's policy AA4010 sets A at 93–100 and A− at 90–92. The Lincoln Memorial University PA program catalog sets A at 90.00–100%. A score of 91% is an A at one institution and an A− at the other.

Use the scale editor to enter your own boundaries. Take them from your school's published grading policy, not from our default and not from memory.

About rounding

Percentages are displayed to two decimal places. Letters are chosen from the unrounded percentage. So 89.5% is a B here, even though it displays as 89.5 and would round to 90 under ordinary rounding.

Many schools round before assigning a letter, and would make that same score an A. We state our rule in full in how this calculator works precisely so you can see where ours and yours would part company.

If you are within half a percentage point of a boundary, this calculator cannot answer your question. Your school's grading policy can.

No advice

Nothing on this site is academic, legal, financial, tax, medical or other professional advice. Nothing here should be used as the basis for a decision that matters — a retake, a course withdrawal, an appeal, an application — without checking it against your school's own rules or speaking to someone qualified: your teacher, academic adviser, registrar or student services office.

For teachers

The printable grading table is a reference sheet produced from the total and the scale you enter. It is a convenience, not a grade record and not a verification of anyone's marks.

Check the printed scale line against your department's policy before you use the sheet, and keep your grades in your institution's own system. Where your department rounds to the nearest whole percent before assigning a letter, a score just below a boundary will differ from this sheet.

Accuracy, honestly stated

We test the arithmetic with an automated suite, drive the whole interface in a real browser before release, and produce every number in every article with this calculator rather than by hand — recording the inputs, the result and the date each time.

We still cannot guarantee the site is free of errors, and we do not. The site is provided "as is", without warranty, as set out in the terms of use.

If a number here is wrong, that is worth our time. Email [email protected] with the mode and the exact values you entered, and we will reproduce it.

External links

We cite external pages, including official grading policies, as sources. We do not control them and they may change after the date we checked. Each citation carries its check date.

In one sentence

Use this site to understand the arithmetic; use your school's grading policy and its official record to know your grade.
