How to answer determine questions is to establish the required answer from the information available. Depending on the subject, this may require calculation, deduction, identification, graphical reading or a chain of reasoning rather than simple recall.
Students sometimes treat determine as calculate automatically. Calculation is common, especially in Mathematics and Science, but the command is broader: the learner must establish the answer using the given information and appropriate method.
This guide explains how to identify the target, decide what method can establish it, show enough working, control units and precision and verify that the result is genuinely supported.
This guide is written for students, parents and educators who want a practical answer to how to answer determine questions in exams. The aim is to turn the command word into a reliable exam routine that can be practised, checked and transferred to unfamiliar questions.
The 60-Second Answer
Identify exactly what must be determined. Review the information provided. Decide whether the answer requires calculation, graph reading, logical deduction, comparison or another method. Carry out the method clearly. State the result with the required unit, precision or label. Check that the result is established by the evidence rather than guessed from memory.
Working definition: A determine question asks the learner to establish an answer using the information available.
Why Determine Questions Matters
Determine focuses on obtaining a definite result rather than merely discussing possibilities.
The command may hide a method-selection problem: the learner must decide how the information can establish the target.
Visible working helps verify that the result comes from valid reasoning and not accidental guessing.
Command words are not decorative verbs. They tell the learner what kind of intellectual work the examiner expects. A student can know the topic and still lose marks by performing the wrong operation.
The Hidden Problem: Determine Is a Result Command With a Method Hidden Inside It
The question may not tell the learner whether to calculate, deduce, read a graph or compare values.
Students who start computing immediately can choose the wrong route.
The first task is to decide what kind of evidence can establish the requested answer.
The Operating Model
Decode Target → Inspect Information → Choose Method → Execute → State Result → Add Unit/Precision → Verify.
Each stage has a separate job. Interpretation identifies what must be produced. Selection chooses the relevant information or principle. Construction turns that into a markable answer. Checking verifies scope, precision and completeness. Retesting shows whether the skill transfers to a changed context.
How to answer determine questions: Step by Step
1. Identify the target
State exactly what value, property, relationship or conclusion must be established.
Keep the target visible.
2. Inspect the available information
Separate relevant facts, data, diagrams, equations or constraints from background detail.
Do not assume every given is needed.
3. Choose the method
Decide whether calculation, graphical reading, deduction, substitution, comparison or another approach can establish the target.
Method selection is part of the task.
4. Execute clearly
Carry out the required steps in a traceable order.
Show enough working for the subject.
5. State the result
Give the established answer directly.
Do not leave it hidden inside working.
6. Add units or precision
Include the correct unit, significant figures, label or condition where required.
Match subject conventions.
7. Check against constraints
Verify that the result fits the data, domain, graph, units or stated conditions.
Reject impossible outcomes.
8. Stop when established
Do not continue calculating or explaining after the answer has been secured unless another command asks for more.
Protect time.
What Strong Performance Looks Like
- The target is explicit.
- Relevant information is selected.
- The method fits the evidence.
- Working is traceable.
- The result is stated clearly.
- Units and precision are correct.
- Constraints are checked.
- The student stops when the answer is established.
These are observable behaviours. They can be modelled, practised and retested. The learner does not need a special exam instinct; the learner needs a reliable sequence of decisions that becomes faster with repetition.
Common Failure Modes
1. Automatic calculation
The learner calculates before deciding whether calculation is needed.
Choose the method first.
2. Wrong target
A related quantity is found.
Restate the required unknown.
3. All-data use
Every given number is forced into the method.
Select relevance.
4. Hidden method
A result appears with no working in a multi-step task.
Show the route.
5. Precision mismatch
The answer uses inappropriate rounding or units.
Follow the prompt and subject conventions.
6. Graph-reading error
The wrong axis, scale or interpolation is used.
Orient before reading.
7. No plausibility check
An impossible result is accepted.
Check constraints.
8. Overworking
The learner continues after establishing the answer.
Stop at the correct depth.
How the Strategy Changes Across Subjects
Mathematics
Determine unknown values, coordinates, gradients, parameters or properties through calculation, algebra, geometry or graph reading.
The disciplinary standard remains decisive. General command-word strategy can organize the response, but subject knowledge determines whether the content and reasoning are actually valid.
Physics
Determine quantities from equations, graphs, measurements or physical relationships with correct units.
The disciplinary standard remains decisive. General command-word strategy can organize the response, but subject knowledge determines whether the content and reasoning are actually valid.
Chemistry
Determine amounts, concentrations, formulae, reaction quantities or identities from data and chemical relationships.
The disciplinary standard remains decisive. General command-word strategy can organize the response, but subject knowledge determines whether the content and reasoning are actually valid.
Data and statistics
Determine values, trends, estimates or categories from tables, graphs and statistical information.
The disciplinary standard remains decisive. General command-word strategy can organize the response, but subject knowledge determines whether the content and reasoning are actually valid.
Primary School, Secondary School and Examination Years
Primary school
Use simple determine tasks where children first say what must be found and then choose the operation or evidence needed.
Keep the routine short, concrete and visible. Adults can model it first, then reduce prompts once the child can perform the decision independently.
Secondary school
Students should practise method selection before execution, especially when graph reading, calculation and deduction appear in the same paper.
Secondary learners should increasingly own scope, evidence, method choice and checking because questions become more varied and time trade-offs more consequential.
Before major examinations
Use mixed determine questions without topic labels so the learner must identify both target and method under time.
Near major exams, mix command words in the same practice set so the learner must first identify what kind of thinking is required.
A Focused 60-Minute Practice Session
- 10 minutes — identify targets and possible methods in five determine prompts.
- 10 minutes — select relevant information.
- 15 minutes — solve two questions with full working.
- 10 minutes — practise graph and table determination.
- 10 minutes — audit units and precision.
- 5 minutes — verify results against constraints.
The exact timings can change. What matters is command identification, independent attempt, feedback, targeted repair and fresh retest.
Diagnostic Checklist
- Is the target exact?
- Is relevant information selected?
- Is the method appropriate?
- Is working visible?
- Is the result stated directly?
- Are units and precision correct?
- Is the answer checked against constraints?
- Does the learner stop when complete?
Use the checklist to identify the earliest decision that failed. A wrong final answer may have begun with command confusion, evidence selection or method choice long before the final line appeared.
Practice Laboratory
Practice 1: Method-before-working
For ten questions, write only the target and intended method.
Do not solve yet.
Practice 2: Relevant-data filter
Cross out givens not needed for one determination.
Explain the choice.
Practice 3: Graph determine
Read values from graphs with careful axis and scale checks.
Include units.
Practice 4: Precision drill
Round results according to varied instructions.
Compare consequences.
Practice 5: Constraint check
Test final answers against domain, geometry, physical scale or chemistry conditions.
Reject invalid results.
Practice 6: Alternative method
Determine the same quantity two ways where possible.
Compare efficiency.
Practice 7: Result-box habit
State the final answer clearly after working.
Prevent hidden results.
Practice 8: Timed mixed set
Complete determine questions requiring different methods.
Track selection delay.
Three Student Cases
Case 1: Maren calculates everything
Maren treats determine as an instruction to use every number.
Her tutor requires method choice before calculator use.
Her routes become shorter and more accurate.
Case 2: Iona reads the wrong scale
Iona understands the graph but misses the axis interval.
She adopts an axis-unit-scale check before extracting values.
Graph determinations improve.
Case 3: Leonie hides the answer
Leonie completes correct working but never states the requested quantity clearly.
She adds a final result line with unit and precision.
Her answers become easier to credit.
How Parents Can Help Without Taking Over
Parents can support determine questions by asking the learner to explain the command and response plan instead of supplying the answer. Useful prompts include: “What does the command word ask you to produce?”, “What information is relevant?”, “What method fits?”, “What would make this incomplete?”, and “How will you check?”
Once the learner can perform the decision reliably, remove the prompt. The goal is independent exam control.
How Tutors Can Use a Three-Student Small Group
In a three-student tutorial, determine questions becomes visible because one learner can attempt, another can challenge whether the command has been satisfied, and the third can check against a rubric, source or mark scheme. Roles then rotate.
After discussion, each learner completes a fresh individual question so shared explanation becomes personal performance.
How to Measure Progress
- Method-selection errors decline.
- Irrelevant-data use falls.
- Graph-reading accuracy improves.
- Units become more consistent.
- Precision errors decrease.
- Working becomes cleaner.
- Plausibility checks increase.
- Determine/calculate confusion decreases.
Marks are the final indicator, but process improvements often appear first: faster command recognition, fewer irrelevant sentences, stronger selection, cleaner working and more reliable checking.

Evidence and Responsible Use
Cambridge International Further Mathematics defines determine as establishing with certainty, while other Cambridge syllabuses describe it as establishing an answer using the information available. The common principle is that the learner must secure the requested result from the provided evidence using an appropriate method.
Command-word meanings can vary slightly by subject and examination board. Use official syllabus wording, teacher guidance and mark schemes as the final standard, while using this framework to build transferable reasoning habits.

Frequently Asked Questions
Is determine the same as calculate?
Not always. Calculation may be the method, but determine can also involve graphs, deduction or other reasoning.
Do I need working?
Use subject conventions and mark allocation; multi-step determinations usually benefit from visible working.
Should I use every value given?
No. Use only relevant information.
How do I know the correct precision?
Follow the question and subject standards for units, decimal places or significant figures.
Can determine be qualitative?
Yes. The result may be a property, identity or relationship rather than a number.
What if there are several methods?
Use a valid efficient method and show enough reasoning.
How do I check the answer?
Use constraints, units, scale, domain and reasonableness.
How do I practise?
Mix calculation, graph-reading and deduction questions so method selection becomes part of the task.
