Mastering the syllabus is only half the battle; the rest is strategy. Exams are a specific skill in their own right, and how you execute on the day often determines the difference between a good grade and a great one.ย
Below is a comprehensive collection of the most effective strategies I have compiled over years of teaching. These techniques are designed to help you command the paper, manage your time ruthlessly, and ensure your final grade reflects your true ability.

Practice past papers under timed, no-note conditions. This helps you get used to the pace and spot where you need to speed up or slow down.

Know exactly which formulas are provided in the booklet and which you must know by heart. Dedicate time to memorising essential formulas and practice applying them until they become second nature. OCR provides a list of these here.

The exam will provide the specific data you need for calculations. However, you are expected to be familiar with its context, variables, and limitations to answer written interpretation questions. Here are summaries of the data sets for each exam board:
Familiarise yourself with command words. These provide instructions and hints for how to write your answer.
1. Calculation and Values
Calculate / Find / Solve / Evaluate
Obtain the final answer. While a correct answer can sometimes yield full marks on its own, you are strongly advised to show your working. If you make a small error without working, you score zero. You may use your calculator, but write down the equation to secure method marks (in case you make an input error).ย
Determine
Obtain the final answer, but you must provide justification or show the specific steps/calculation used to reach it.
Exact
Give the answer as a fraction, surd, or in terms of ,, or e. Never use rounded decimals.
Estimate
Use the provided information or a mathematical model (e.g. trapezium rule, Newton-Raphson, small-angle approximations) to find an approximate value. Do not try to calculate the exact answer.
2. No Workings Required
State / Write down / Give
No working out is required. The answer should be obvious from the question, a graph, or your calculator.
Identify
Select the correct answer from a list, a set of options, or a graph.
3. Logic and Proof
Prove
A formal, rigorous argument. You must clearly define any variables used, show clear logical steps, and finish with a formal concluding statement.
Show that
You are given the answer; your job is to prove it is true. You must show every single step of the derivation; do not risk skipping lines of algebra just because you can do them in your head. You must finish with a concluding statement.
Show detailed reasoning
You must demonstrate the detailed analytical method used to solve the problem. You may use a calculator to check values or perform arithmetic, but the logical steps must be fully written out on the page.
Verify
Substitute a value into an equation or statement to demonstrate that it works.
Hence
You must use the result found in the previous part of the question. Any other method, even if correct, typically scores zero marks.
Hence or otherwise
You should use the previous result (itโs usually faster), but other valid methods are permitted.
Deduce
Use a previous result to find the answer with a little thinking. Minimal working is required.
4. Written and Contextual
Explain
Provide a concise written answer using correct mathematical vocabulary. If relevant, support your explanation with a calculation.
Interpret
Translate a mathematical result into a written statement about the real-world context (e.g. "The gradient represents the cost per item").
Comment on
Analyse your results. This often involves comparing your calculated value to a real-world fact or judging if a model is realistic/valid.
Compare
State a similarity or difference between two things. You must explicitly mention both items in your answer.
5. Graphing and Visuals
Sketch
Draw the general shape of the curve without graph paper. You must label key features such as axes intercepts, turning points, intersections and asymptotes (using dashed lines).
Plot
Mark specific points accurately on a grid and join them if required.
Draw
Create a diagram with appropriate accuracy. Include any labels, annotations, lengths or angles as these may justify marks.

Start from the beginning and work your way through. Early questions are easier and can boost your confidence. Label each section (e.g., (a), (b), (c)) so examiners can easily follow your work.
๐ง ๐ ๐ผ๐๐ฒ ๐ข๐ป ๐ช๐ต๐ฒ๐ป ๐ฌ๐ผ๐'๐ฟ๐ฒ ๐ฆ๐๐๐ฐ๐ธ
Don't get bogged down on a single question. If you are stuck, place a star โฑ next to it and move on. Returning to the problem later with a fresh perspective is more effective than staring at it for five minutes without progress. You will maximise your marks by maintaining your momentum.
โณ ๐๐ถ๐บ ๐ณ๐ผ๐ฟ โ๐ข๐ป๐ฒ ๐ ๐ฎ๐ฟ๐ธ ๐ฝ๐ฒ๐ฟ ๐ ๐ถ๐ป๐๐๐ฒโ
The number of marks should guide your timings. Sticking to this pace gives you a 20-minute 'safety buffer' at the end to check your work and return to the hard questions you starred.
โ๏ธ ๐ ๐ฎ๐๐ฐ๐ต ๐ฌ๐ผ๐๐ฟ ๐ ๐ฒ๐๐ต๐ผ๐ฑ ๐๐ผ ๐๐ต๐ฒ ๐ ๐ฎ๐ฟ๐ธ๐
The mark allocation indicates the expected complexity and depth of your solution. Use it to guide how much you write.
1 Mark: Write the answer. These are usually โstateโ or โwrite downโ questions. Typically, no workings are required. If the calculation feels complex, re-read the question: youโve likely missed a shortcut.
2-4 Marks: Show your working. Method marks are often awarded even if the final answer is incorrect, so make your steps clear.
5+ Marks: A short answer here is a red flag. It suggests you have oversimplified the problem or relied too heavily on your calculator. These questions demand a rigorous, logical chain of reasoning.

A big, clear diagram can help simplify complex problems: vectors, coordinate geometry, trigonometry, normal distribution, force diagrams, etc. Visuals make it easier to process and understand all the information.
โ๏ธ ๐ฆ๐ต๐ผ๐ ๐ฌ๐ผ๐๐ฟ ๐ช๐ผ๐ฟ๐ธ๐ถ๐ป๐ด๐
Answers without working may not gain full credit. Even if you can do it in your head, write it down. Always quote the formula you are using before you use it. Even if your final answer is wrong, you can still earn method marks.
โฉ ๐๐๐๐ฒ๐บ๐ฝ๐ ๐๐น๐น ๐ฃ๐ฎ๐ฟ๐๐ ๐ผ๐ณ ๐๐ต๐ฒ ๐ค๐๐ฒ๐๐๐ถ๐ผ๐ป, ๐ช๐ต๐ฒ๐ฟ๐ฒ ๐ฃ๐ผ๐๐๐ถ๐ฏ๐น๐ฒ.
If you canโt answer part (a), you may still be able to answer the other parts. You can still earn follow-through marks, even if you suspect your earlier answers are incorrect. If part (a) is a โshow thatโ and you canโt prove it, assume the result is true and use it in (b).
๐ ๐๐ผ๐ผ๐ธ ๐ณ๐ผ๐ฟ ๐๐ถ๐ฑ๐ฑ๐ฒ๐ป ๐๐ถ๐ป๐ธ๐
Questions often build on one another, even without the word "Hence". If you are stuck, review your previous work. The result from part (a) is sometimes the key to unlocking part (b).
๐ฆ ๐๐ถ๐ป๐ฑ๐ถ๐ป๐ด ๐๐ต๐ฒ ๐ฃ๐ฎ๐๐ต
For complex, high-mark questions, you rarely see the full path to the solution immediately. Do not stare at the blank page. Instead, write down a relevant formula, draw a diagram, or perform any logical calculation with the given values. This momentum helps you secure early method marks and often helps reveal the rest of the path as you work.
๐งฉ ๐จ๐๐ฒ ๐๐๐ฒ๐ฟ๐ ๐ฃ๐ถ๐ฒ๐ฐ๐ฒ ๐ผ๐ณ ๐๐ป๐ณ๐ผ๐ฟ๐บ๐ฎ๐๐ถ๐ผ๐ป
If the question gives you a value, a diagram, or any extra condition, itโs likely there for a reason. If youโve finished but havenโt used all the information, youโve probably made a mistake. Pause and ask: Why did they tell me this? Unused information is often a clue that your method, interpretation, or model is incomplete.
๐ ๐๐ฎ๐ป ๐ ๐๐๐ฒ ๐บ๐ ๐ฐ๐ฎ๐น๐ฐ๐๐น๐ฎ๐๐ผ๐ฟ ๐ต๐ฒ๐ฟ๐ฒ?
For commands like "Find", "Calculate", "Evaluate" or "Solve", you may use your calculatorโs advanced functions (e.g. polynomial solver, inequality solver, simultaneous equation solver) to save time. However, always write down the equation you are solving first. This acts as your "working out" and secures method marks if you make an input error.
However, you must show full algebraic working if:
The question contains โshow all stages of your workingโ or requests โdetailed reasoningโ.
The command words are โProveโ, โShow thatโ, โDetermineโ, or "Solve algebraically".
The question asks for an โExact valueโ (your calculator may not give you the exact answer).
In these cases, use your calculator only to check your final answer. A correct answer without a supporting method will likely score zero marks.
Also, for Edexcel:
"Solutions relying entirely on calculator technology are not acceptable" means your calculator is an assistant. You can use it for "grunt work" (arithmetic, evaluating logs, roots), but you cannot use it to completely bypass the actual method being tested.
"Solutions relying on calculator technology are not acceptable" means your calculator is banned. Your work must look as if you do not own a calculator.

The questionโs specific wording often tells you how many answers are required.
โFind the value...โ / โEstimate the root...โ
Expect a single answer. If you find two, check if one needs to be discarded.
โFind the values...โ
Expect multiple answers. If you only find one, you may have missed a solution (e.g. by dividing by a variable instead of factorising).
โFind the set of values...โ / โFind the range of values...โย
Expect an inequality.
โFind the coordinates...โ
Donโt just find x and stop! Find the corresponding value of y and write the answer as a pair (x,y).
โ ๏ธ ๐๐ต๐ฒ๐ฐ๐ธ ๐ฎ๐ป๐ฑ ๐ฅ๐ฒ๐ท๐ฒ๐ฐ๐ ๐๐ป๐๐ฎ๐น๐ถ๐ฑ ๐ฆ๐ผ๐น๐๐๐ถ๐ผ๐ป๐
Correct algebra can produce answers that are mathematically impossible or contextually wrong. You must explicitly reject these to gain full marks.
Constraints:
Restricted Domain: Is the solution in the domain of the function?
Logarithms: You can only log numbers greater than 0.
Square Roots: You can only root numbers greater than or equal to 0.
Denominators: A solution that makes the denominator 0 is undefined (asymptote).
"Ghost" Solutions:
Squaring: If you squared both sides to solve, you may have created extraneous solutions. Check them in the original equation.
Modulus Equations: You may have found extraneous solutions. Check them in the original equation.
Out of Bounds:
Trigonometry: Is the solution inside the given interval (e.g. 0 < x < 360)?
Small Angle Approximations: Is the answer small and in radians?
Binomial Expansion: Is the input x valid for the expansion range?
Geometric Series: Is -1 < r < 1 for the series to be convergent?
Context:
Physical Quantities:
Time, mass, distance, and speed are scalar quantities and cannot be negative.
Displacement, velocity, and acceleration are vector quantities and can be negative.
Probability: Must be between 0 and 1.
Models: Is the answer sensible in the real-world context?

If you realise you have made a mistake, draw a single, neat diagonal line through the work.
If you replace it: Examiners will ignore the crossed-out work and mark the new attempt.
If you do not replace it: Examiners will mark the crossed-out work (provided it is legible).
Do not scribble it out completely: You may need to refer back to it, or you may realise it was actually correct!
Donโt overwrite: Never turn a "3" into a "5". Cross out the old number and write the new one clearly alongside.
โ ๏ธ ๐ ๐๐น๐๐ถ๐ฝ๐น๐ฒ ๐๐๐๐ฒ๐บ๐ฝ๐๐
Always clearly cross out attempts you do not want marked. If you leave two attempts uncrossed:
Edexcel: Marks the final attempt that is most complete.
AQA: Marks the best attempt (but may withhold marks if the answers contradict each other).
OCR: Marks the last attempt (unless it is substantially less complete).
โ๏ธ Degrees or radians?
Check your mode before every problem.
If you see a ฯ symbol, youโre in radians, and if you see a ยฐ symbol, youโre in degrees.ย
For differentiation and integration of trig functions, you MUST be in radians.
โ ๏ธ ๐๐ผ๐ปโ๐ ๐๐ผ๐ฟ๐ด๐ฒ๐ +๐ฐ ๐ฎ๐ป๐ฑ ยฑย
Indefinite integrals always include a โ+cโ.
Rooting an equation produces positive and negative solutions: if xยฒ = 4, then x = ยฑ2.
However, evaluating a square root yields only the positive result: โ4 = 2.ย
โ๏ธ ๐๐ต๐ฒ๐ฐ๐ธ ๐ต๐ผ๐ ๐๐ผ๐๐ฟ ๐ณ๐ถ๐ป๐ฎ๐น ๐ฎ๐ป๐๐๐ฒ๐ฟ ๐๐ต๐ผ๐๐น๐ฑ ๐ฏ๐ฒ ๐๐ฟ๐ถ๐๐๐ฒ๐ป.
Exact form or decimal? Do they want set notation? Do they want a specific equation form (e.g. ax + by + c = 0)? Column vector or i and j vector notation? Degrees or radians?
๐ Check Units
Ensure all units are consistent before calculating (e.g. matching km/h with hours).ย
Check if the question requires a specific unit for the final answer.ย
Missing or incorrect units can lose a mark, even if the numerical value is correct.
๐ฏ Check Accuracy
Always check the required level of accuracy (e.g. 3 significant figures, 1 decimal place).ย
When no specific degree of accuracy is stated, three significant figures is normally acceptable for final answers.ย
Avoid rounding until your final answer.
๐ท๏ธ Check Variables
If a question asks to find an equation linking variables H and t, you must use them in your final answer. Writing a generic equation like y = mx + c instead of H = mt + c will lose the final accuracy mark.ย
Check the variableโs scale: "population P, measured in thousands" means that if the question gives you 5,000 people, you must substitute P = 5 into the equation.ย
Check how the variable is defined:
Relative wording: If t is defined as "years after 1990", then for 2005, use t = 15, not t = 2005.
Cumulative wording: If a model gives you the โtotal sales after t monthsโ but asks for sales specifically โin the 5th monthโ, you will need to find the difference between t = 5 and t = 4.
๐ค ๐๐ต๐ฒ๐ฐ๐ธ ๐๐ผ๐ด๐ถ๐ฐ
Ask yourself: Does this make sense? A car going 400mph? A coefficient of friction of =9.2? A negative variance? If something looks wrong, go back and check your workings.
๐ Define Inverse Functions Fully
To fully define a function, you must state its domain. When finding fโปยน(x), always state its domain, even if not explicitly asked. This is often worth a mark. Tip: The domain of the inverse is the range of the original function.
๐ ๐๐ผ๐ป๐๐ฒ๐ ๐๐๐ฎ๐น๐ถ๐๐ฒ ๐ถ๐ป ๐ฆ๐๐ฎ๐๐ถ๐๐๐ถ๐ฐ๐
In statistics, remember to relate your answers to the context. When interpreting answers, critiquing assumptions, or concluding hypothesis tests, ensure your response relates back to the real-world scenario.
๐ข ๐๐ฒ ๐ฃ๐ฟ๐ฒ๐ฐ๐ถ๐๐ฒ ๐๐ถ๐๐ต ๐ฅ๐ผ๐๐ป๐ฑ๐ถ๐ป๐ด
Keep the full calculator values throughout your workings by using the ANS or STO functions, and round only at the end to avoid introducing errors. In mechanics, use g = 9.8 m/sยฒ unless the question specifies otherwise, and make sure any final answers that rely on this value are rounded to three significant figures.
โ ๏ธ "๐ฆ๐ต๐ผ๐ ๐ง๐ต๐ฎ๐" ๐ ๐ฒ๐ฎ๐ป๐ ๐ฆ๐ต๐ผ๐ ๐๐ ๐๐

Sometimes examiners are very strict with โshow thatโ questions. Your final answer should match the given form exactly: same structure, letters, and order. If they want โS=ยฝMgcotฮธโ, then concluding with โS=ยฝcotฮธMgโ can (unfairly) lose you a mark. Be precise in your final step.

Misreading or misinterpreting questions are common pitfalls; take your time to read and understand whatโs being asked carefully. Work through the problem one step at a time, pausing regularly to review your reasoning and calculations. Before moving on, double-check your answer to confirm youโve addressed every element of the question.
๐ข ๐๐ฎ๐น๐ฐ๐๐น๐ฎ๐๐ผ๐ฟ ๐๐ฟ๐ผ๐๐โ๐๐ต๐ฒ๐ฐ๐ธ
Recalculate tricky expressions.ย
Use the powerful functions on your calculator to double-check quadratic/cubic equations, quadratic inequalities, simultaneous equations, definite integrals, derivative evaluations, and summations.ย
Substitute your solution back into the original equation to confirm it holds true.
On the CG50, you can check the solutions to sinx = tanx by graphing y = sinx and y = tanx and finding their intersections.
๐ ๐๐ถ๐ป๐ฎ๐น ๐ฅ๐ฒ๐๐ถ๐ฒ๐
At the end, go through your paper with fresh eyes. Confirm that every part is answered, and the calculations are accurate. If time allows, redo tricky questions without looking at your original solution: you're unlikely to make the same error twice.
The Day Before
๐ค Sleep: Prioritise 8 hours of sleep over late-night cramming. A tired brain makes calculation errors.
๐ Equipment: Pack your clear pencil case: spare black ballpoint pens, sharp pencils, ruler, eraser, highlighter. A compass is useful for accurate circle sketches.
๐งWater: Pack a clear water bottle with the label removed.
๐ Calculator: Remove the lid and check the battery/charge.ย
๐ ID: Pack your student ID card.
The Morning Of
๐ณ Nutrition: Eat a slow-release energy breakfast (porridge, oats, eggs, toast).
๐ Clothing: Exam halls are unpredictable. Wear a t-shirt with a hoodie/jumper over it so you can adapt to the AC or heat.
๐ Calculator: Ensure "Exam Mode" is active (e.g. FX-CG50, Numworks). Set to Degrees mode for Statistics and Mechanics.
๐ฅช Afternoon Exams: Eat a proper lunch. Stick to light revision only: flashcards and formulas.
โฑ๏ธArrival: Arrive early to avoid stress, and visit the bathroom before entering.
Just Before You Start
๐ฐ๏ธ Clock Visibility: Locate the clock. If it's not visible, tell the invigilator.
๐ช Wobbly Desk: If your desk wobbles, ask for a folded sheet of paper.
๐ง Brain Dump: Once the exam starts, flip to the first blank page and write any formulae not provided that you typically forget.
