Gradebook and GPA planner — what you need on the final
Enter each assessment with its weight, and see your projected grade, your best possible grade, and the exact score you still need to finish where you want. Your courses stay in your browser.

Edit these to match your institution. Thresholds and grade points are not standard — a 4.0 scale at one university starts an A at 90, at another at 85.
How it works
- 1
Add a course and its assessments
Give each piece of work its weight from the syllabus — 40% for the final, 5% for a quiz. Leave the score blank until it comes back marked; an unmarked item is treated as unknown rather than as a zero, which is the difference between a projection and a scare.

Set your grade scale
The default is a common 4.0 scale, but thresholds are not standard. An A starts at 90 in one institution and 85 in another, so edit the bands to match yours before trusting the letter grade.

Read the target line
It shows the score you need across everything still to be marked. When that number goes above 100 it says so plainly, because a target that is no longer reachable is worth knowing in week eight rather than in the exam hall. When it comes out below zero, the grade is already secured and the tool says that too.
Frequently asked questions
How is the projected grade calculated?
It assumes the work still to be marked goes the same way as the work already marked. That is a more honest default than assuming full marks, which is what most grade calculators show and which always looks encouraging.
What is the difference between projected and best possible?
Projected continues your current average. Best possible assumes 100% on everything remaining. The gap between them is how much is still in your hands.
Why does my weighted average differ from a simple average?
Because assessments are not worth the same. Averaging 95 on a 5% quiz with 60 on a 40% exam gives 77.5 as a simple average and a much lower number once weight is applied. Forgetting weight is the single most common gradebook mistake.
Is my data uploaded?
No. Courses, marks and your grade scale stay in your browser using local storage, so they are still there when you come back after the next assignment is returned. Nothing is sent anywhere, and clearing your browser data removes them.
Why is a course with no marks yet excluded from my GPA?
Because it has no grade yet. Counting it as zero would drag down the GPA for a semester that has barely started, which is worse than saying nothing.
My weights do not add up to 100 — is that a problem?
The tool warns you and keeps working, because partial syllabuses are common mid-semester. But if the total is wrong the projection will be too, so it is worth checking against the course outline.
What score do I need on the final to get an A?
That is the one number this tool exists to produce. It works backwards from the grade you are aiming at: it takes the marks already banked, subtracts them from the total the grade requires, and divides what is left across the weight still unmarked. If your final is worth 40% and you are 6 percentage points short of the boundary, you need 15 points of that 40 — which is 37.5% on the paper, not 94% as the raw gap makes it look.
What happens if I have several pieces of work left, not just a final?
The target is the average you need across all of them, weighted. That is more useful than a per-assignment figure, because the pieces are rarely worth the same and you can trade a weaker quiz against a stronger essay. If you want a specific plan rather than an average, enter a predicted score on the pieces you are confident about and the target recomputes for what remains.
Why does the projected grade go down when I enter a good mark?
Because the projection assumes the rest of the course goes the way the marked work has gone, and a mark that is good in absolute terms can still be below your running average. A 78 entered when you are averaging 84 pulls the projection down, correctly. Grade calculators that always assume full marks on the remainder never show this, which is exactly why they are reassuring and not useful.
Can I plan several courses and see a semester GPA?
Yes. Each course produces its own letter grade and grade point from the scale you set, and the GPA is the credit-weighted average of the courses that have a grade. Courses with no marks entered are left out rather than counted as zero, so a semester that has barely started does not show a GPA of 0.4.
What is the difference between GPA and CGPA here?
GPA is the average for the set of courses you have entered; CGPA at your institution is the average across everything you have ever taken. To approximate a CGPA, enter your completed courses with their final grades alongside the current semester. The result is still a planning figure — institutions apply their own rules on resits, capped grades and excluded courses, and none of those are known to this page.
Do grade boundaries really differ that much between institutions?
Enough to change your letter. An A commonly starts at 90 in North America and at 80 or even 75 in Malaysian, British and Australian institutions, and some scales carry an A+ worth more than 4.0 while others cap at 4.0. That is why the bands here are editable and why nothing is preset to a national standard — the letter is only as right as the scale you enter, so it is worth two minutes with the course outline.
Does this match my university’s official GPA?
Only if the scale you enter matches theirs. Some institutions round differently, exclude certain courses, or cap grade points. Treat this as planning, not as a transcript.
