Example: protect checking time, then allocate working minutes
- Working time120 − 15 = 105 minutes
Reserve fifteen minutes for checking.
- Time per mark105 ÷ 100 = 1.05 minutes
Divide by marks for the required answers.
- Twelve-mark question1.05 × 12 = 12.6 minutes
That is twelve minutes and thirty-six seconds.
Give each question a starting time budget
An exam can feel more manageable when you know roughly how much time a question's marks justify. This calculator reserves a chosen amount of checking time, then divides the remaining working time in proportion to marks. It gives a planning allowance for one question rather than predicting how quickly you will solve it.
Use the result before a practice paper or while preparing a pacing sheet. A question worth more marks receives more time under this model, but mark value is not a perfect measure of difficulty. Essay planning, unfamiliar calculations and reading long instructions can create different demands. The allowance is a reference point you can adapt using the paper's instructions and your practice experience.
Match the inputs to the paper you must answer
Enter the full exam duration in minutes, converting hours where necessary. A two-hour paper is 120 minutes. Enter the checking time you want to protect at the end, then the total marks for the required set of answers. Finally enter the marks assigned to the question you are budgeting.
The checking reserve must be smaller than the exam duration, leaving positive working time. Question marks must be positive and cannot exceed the entered total. If the paper offers optional questions, do not count every printed option as compulsory workload. Use the marks associated with the combination you are required to answer. Follow any separately timed sections rather than treating restricted section time as freely available across the entire exam.
Subtract the reserve before dividing by marks
Working minutes equal Exam minutes minus Checking minutes. Divide working minutes by total marks to find minutes per mark, then multiply that rate by the question's marks. The formula is: Question minutes = (Exam minutes − Checking minutes) ÷ Total marks × Question marks. The reserve is removed once from the whole paper, not once for every question.
This method allocates all working time across the required marks when every question is included exactly once. If you calculate individual allowances and round them separately, their displayed sum may differ slightly from the original total. Keep the overall end time visible and allow for rounding when preparing a pacing sheet. The calculation does not automatically create a timetable or assign clock-based start and finish times.
Budget a twelve-mark question in a two-hour paper
Suppose an exam lasts 120 minutes and you reserve fifteen minutes for checking. That leaves 105 working minutes. The required questions total one hundred marks, so the proportional rate is 105 ÷ 100 = 1.05 minutes per mark. A twelve-mark question receives 1.05 × 12 = 12.6 minutes.
The decimal part is a fraction of a minute: 0.6 × 60 = 36 seconds. Therefore, 12.6 minutes means twelve minutes and thirty-six seconds, not twelve minutes and six seconds. In a practical plan, you might use a nearby whole-minute checkpoint while keeping the full-paper total intact. A twenty-mark question in the same paper receives twenty-one minutes because its mark value is proportionally larger.
Notice the trade-off created by a larger reserve
Keeping the same 120-minute, one-hundred-mark paper but reserving twenty minutes leaves one hundred working minutes. The rate becomes one minute per mark, and the twelve-mark question receives twelve minutes. Reserving only ten minutes leaves 110 working minutes, giving that question 13.2 minutes. More checking time means less first-pass time, not more time overall.
Choose a reserve you can defend from practice rather than treating the example as a recommendation for every exam. Some students need extra checking for arithmetic, answer transfer or question-number matching; some papers require more initial reading. If you want to reserve time for both reading and final checking, include their combined protected amount in the reserve and document that choice in your own plan.
Watch for optional sections and uneven question demands
If a paper asks you to answer two of three twenty-mark essays, the required essay total is forty marks, not sixty. Counting unused options enlarges the denominator and shortens every allowance incorrectly. Check the required combination carefully, especially when some compulsory sections and some optional sections appear together.
A one-mark item and a twenty-mark response may involve different setup costs, so strict proportional timing may need adjustment. Use the calculated budget to spot large overruns, then adapt it to the specific paper. Do not assume that reaching an allowance means you must abandon an answer immediately; consider instructions, remaining marks and your progress. Equally, do not spend the entire exam pursuing one difficult question while leaving required work untouched.
Turn allowances into useful checkpoints
During a practice paper, note when you start and finish each section. Compare the actual time with the proportional budget and identify whether the difference came from reading, planning, calculation or checking. Adjust your strategy based on repeated experience, while keeping the total exam duration fixed. More detailed evidence is useful than simply deciding you are slow at a subject.
Before the real paper, prepare a simple set of section checkpoints if permitted, then follow all examination rules about notes and timing devices. During the exam, keep track of remaining time and unanswered marks. Protect the final review allowance where practical, and use it for specific checks rather than starting an unnecessary rewrite. The calculator supports pacing decisions; it cannot guarantee completed answers, correct work or any particular score.
If a question has several parts, compare their individual marks before dividing its total allowance equally. A two-mark definition and a ten-mark explanation need not receive the same share. Your within-question plan can follow the same proportional reasoning while allowing for reading the shared prompt.
Frequently asked questions
Do I include optional questions I will not answer?
No. Use the total marks for the required combination of answers. If you must choose two of three equal-mark essays, count two essays in that total. Otherwise the calculator would allocate time to work you are not required to complete.
Does 12.6 minutes mean twelve minutes six seconds?
No. Multiply the decimal part by sixty: 0.6 minutes is thirty-six seconds. The full allowance is twelve minutes thirty-six seconds. Decimal minutes and a minutes-and-seconds clock display represent time differently, so convert before setting a checkpoint.
How much checking time should I reserve?
The calculator does not prescribe a reserve. Choose it using the paper’s format, instructions and your practice experience. Make sure it leaves enough working time, then compare different reserves to see how they change the per-question allowances.
Can I use this for separately timed sections?
Calculate each timed section separately with its own duration, reserve and required marks. A full-paper average can be misleading when you cannot transfer unused minutes between sections. The official timing rules take priority over any proportional plan.
