Current grade, weights, target and floor are all editable because syllabi differ; the tool computes with your numbers and asserts no school's policy. Below: the formula, reading an impossible answer honestly, and why the tool is most useful weeks before the exam.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Score needed on the final
Runs in your browser; nothing is sent or stored. Current grade weight 60 and final weight 40 is only a starting point: your syllabus rules. The minimum field models courses that require a floor score on the final itself; leave it at 0 if yours has none.
The formula, in one line
Call the target t, your current grade g, and the current grade's weight w as a fraction. The final's weight is one minus w, and the needed score is t minus g times w, divided by one minus w. Standing at 72 with the coursework worth 60 percent and a target of 80: the final must deliver 92. The calculator runs this on every keystroke, which turns target setting from arithmetic homework into a slider you can feel.
When the answer is above 100, believe it
A required score above 100 is not a bug; it is the honest reading that the target closed. The productive response is triage: lower the target to the best reachable grade and see what that requires, or move the effort to a course where the arithmetic still bends. Discovering this in week ten instead of exam night converts a bad surprise into a plan, and the calculator's whole value is making that discovery early and undramatic.
The minimum score rule, modeled honestly
Some courses fail any student whose final falls below a floor, regardless of the average; the syllabus states it when it exists. Enter that floor and the tool shows the larger of two numbers: what the average demands and what the floor demands, with a status line saying which rule is speaking. If your course has no such rule, leave the field at zero and the pure average answer stands. The distinction matters exactly when your coursework is strong and the temptation to coast is real.
Use it early: the week one reading
The calculator is usually opened in exam week, and that is its least useful moment. Open it in week one with a hypothetical: if I hold homework and quizzes at 85, the final only needs 60 for my target; at 70, the final needs 85. That difference prices weekly discipline in exam points, the only currency students actually feel. The number that motivates is not the average you have; it is the final score you are quietly signing up for.
Where this sits in WeSolve+
Knowing the number is the easy half; scoring it is study. Upload the course PDF to WeSolve+, get questions with the reasoning attached, and let spaced repetition return your misses until exam day. Companion tools: current grade first, this page second, and exam grade after the papers return.

| Current grade | Needed on the final | Reading |
|---|---|---|
| 50 | 100,0 | Exactly everything |
| 60 | 85,0 | Hard but real |
| 70 | 70,0 | Hold the line |
| 80 | 55,0 | Earned slack |
| 90 | 40,0 | Floor rules may apply |
| Target 85 instead | Add 37,5 to each | Targets are expensive |
How do I calculate what I need on the final?
Subtract your current grade times its weight from the target, divide by the final's weight. The tool computes it live with a floor rule included.
What if the answer is above 100?
The target is out of reach through the final alone. Lower the target or redirect effort; the early warning is the tool's real value.
What is a minimum score rule?
Some syllabi fail the course if the final itself falls below a floor, regardless of the average. Enter the floor and the tool applies whichever rule binds.
What weights should I enter?
The syllabus percentages: coursework weight in the weight field, and the final's weight is the remainder. Sixty forty is only a common starting point.
When should I use this calculator?
Week one, with hypotheticals: it prices weekly discipline in exam points. Exam week readings are accurate but late.
Is anything uploaded?
No. The calculation runs in your browser; nothing is sent or stored.
