How to use

What it's for

Find out what score you still need on the parts of one course you have not taken yet — usually the final exam — to reach the final grade you want.

Before you start

Have your syllabus, which says how much each part of the course is worth (its weight), and the scores you have so far, as percentages.

  1. Set your target

    Type the final grade you are aiming for in Target final grade, as a percentage, such as 85.

  2. List each part of the course

    Replace the example rows with your own: a name, its Weight % from the syllabus, and your Score % if you already have it.

  3. Leave future scores blank

    Leave Score % empty for anything you have not taken yet. A blank means "not yet", while 0 means you scored zero — the two give very different answers.

  4. Add rows until the weights reach 100%

    Press + Add component for each missing part, and ✕ to remove one. Weights entered, beside the target, should read 100% once every part is listed.

  5. Press Calculate

    Press Calculate. The answer at the top already changes as you type; the button brings it back into view.

Reading the result

  • Needed on what is left: the average score you need across every part still blank. Once every score is in, it reads Final grade instead.
  • Secured or Out of reach: shown instead of a number when even a zero still reaches your target, or when even a perfect score would not.
  • Standing so far: your average over the parts already graded.
  • Best still possible and Worst still possible: your final grade if you score full marks, or zero, on everything left.

If it goes wrong

  • It says Out of reach: a perfect score on what is left still falls short. The line under it gives the best grade you can still reach — aim for that instead.
  • Weights entered is below 100%: part of the course is missing, so the answer is not reliable yet. Add the missing parts with + Add component.
  • An error says the weights add up to more than they can: a weight was typed wrongly or twice. Check each Weight % against the syllabus.

What this is

The question near the end of a term is not what your average is — it is what you still need. Enter each part of the course with its weight, fill in the scores you already have, and leave the ones you have not sat blank.

Alongside the answer are the two figures that decide whether the question is worth asking: the best grade still reachable if you ace everything left, and the worst if you score nothing. When the target sits outside that range, the tool says so rather than quoting a score above 100.

Questions

How do I say a component has not been graded yet?

Leave its score blank. A component with a weight but no score is what is still to come, and the answer is the average you need across all of them. That is the whole model — a blank is meaningful here, not a gap.

Why does it say "Out of reach" instead of the number I need?

Because the number would be above 100. If a perfect score on everything left still lands below your target, the target is not hard — it is arithmetically impossible, and the result says which grade a perfect score would actually give you. Aim at that instead.

What does "Secured" mean?

That you have already banked enough points to hit the target no matter what happens next, including a zero. The worst-still-possible figure alongside the result shows where a zero would leave you.

My weights do not add up to 100. Is that a problem?

The tool tells you what they add up to and still gives an answer, scaled to what you entered, so it stays useful while you are typing a syllabus in. But the figure is only trustworthy once every component is listed — a missing 20% is 20% of your grade unaccounted for.

Is this the same as a GWA calculator?

No. A GWA calculator averages grades you already have across subjects. This works within one subject and looks forward: it takes what you have scored so far and tells you what the rest has to be.

The maths

What you need
target − banked
weight left
100
Worked
Quizzes 20% at 90, midterm 30% at 75, final 50% to come
18 + 22.5 banked 40.5 points
target 80 − 40.5, over 50% 39.5 ÷ 50
Needed on the final 79.00%

Note that 40.5 points is not a grade of 40.5 — it is 81% of the half of the course that has been graded so far.

When it cannot be done
60% at 40, targeting 90 needs 165%
Best still reachable 64.00%

A tool that prints "you need 165" invites you to read it as merely hard. It is not hard, it is impossible, and knowing the real ceiling is more useful than the impossible number.
