A Level marks can fall across several subjects when a student knows the content but answers a different command word from the one on the paper. The fix is to identify the verb in every question, practise the response it requires, and check that each paragraph keeps answering that exact instruction.
Three papers sat open on the desk. On one, the student had explained clearly but had been asked to assess. On another, they had described several points when the question asked them to analyse the relationship between them. The third answer had included strong knowledge, yet the instruction was to compare.
Different subjects. Different topics. The same repeated mistake.
This is frustrating because the work can look convincing at first glance. There are correct terms, relevant examples and full paragraphs. Yet exam marks depend on the task set by the command word. An answer can be accurate and still leave marks behind if it does not make the required judgement, show the required reasoning or reach the required comparison.
The command word sets the job
A question’s command word tells you what kind of evidence the examiner needs to see. Treat it as the job description for the answer.
“Describe” usually calls for clear characteristics or steps. “Explain” asks for reasons, links or consequences. “Analyse” requires you to break an issue into parts and show how they connect. “Evaluate” asks for a judgement supported by evidence, often with limits or alternative views considered. “Compare” needs direct points of similarity and difference, rather than two separate descriptions placed side by side.
The exact expectations depend on the subject, syllabus and mark scheme. That is why a student preparing for Cambridge International A Levels benefits from practising with the language used in their own course materials, rather than relying on a generic list of exam verbs.
Before writing, underline the command word and turn it into a short instruction. For example: “I need to make a supported judgement,” or “I need to show two direct comparisons.” Keep that instruction visible while planning.
Strong knowledge needs the right measurement system
In 1999, NASA lost the Mars Climate Orbiter while the spacecraft approached Mars. The investigation found that a ground software file used pound-seconds while NASA’s navigation system expected newton-seconds. The mission had detailed calculations and sophisticated engineering, but the information was being handled in incompatible units.
NASA’s Mars Climate Orbiter Mishap Investigation Board documented the failure in its Phase I Report. The lesson was not that calculation did not matter. Calculation mattered so much that one mismatch in how it was expressed sent the mission off course.
Exam answers have a smaller, kinder version of the same problem. A student may bring good knowledge to a question, but the answer needs to be expressed in the form the question measures. An evaluation written as an explanation can drift off course. A comparison made from two isolated mini-essays can do the same.
This is why re-reading the question after each paragraph matters. Ask: “Have I done the verb?” It is more useful than asking only, “Have I included enough facts?”
Build a response that keeps returning to the task
A practical routine can make command words visible throughout revision and timed practice.
Start by making a small command-word bank for each subject. Use examples from past papers or teacher feedback, then write one sentence describing what each instruction requires in that subject. A history evaluation and a biology evaluation may both involve judgement, but the evidence and structure will differ.
Next, plan with the verb in mind. For an analyse question, list the links you need to show. For an evaluate question, decide what judgement your conclusion will reach before you begin drafting. For a compare question, pair each point directly: similarity, difference, evidence.
Then use a final check before moving on:
- Circle the command word again.
- Underline the sentence in each paragraph that fulfils it.
- If you cannot find one, revise the paragraph’s opening or closing sentence.
- Check that the conclusion answers the same question, rather than repeating notes from the body.
A paper review can reveal patterns that are difficult to spot alone. If comments repeatedly say “more analysis,” “answer the question” or “develop your evaluation,” gather those comments in one place. They may point to one habit across subjects rather than separate weaknesses in economics, literature or science. First Practice Paper Review: How Command Words Can Hide Strong Knowledge explores that pattern in more detail.
Practise precision before the next paper
Command words deserve practice in their own right. Take one topic you already know and answer it three ways: describe it, explain it, then evaluate it. The content may overlap, but the structure and final sentence should change each time.
For parents, this creates a more useful conversation after a mock result. Instead of asking only why the mark was lower than expected, ask which command words caused difficulty and whether the student’s answer matched them. That question can turn a vague concern into a revision plan.
The Mars Climate Orbiter investigation showed how costly it can be when a system receives the right information in the wrong form. In an A Level answer, the stakes are far lower, and the correction is available before the next paper: read the verb, plan for the verb, and make every paragraph prove that you answered it.
