How IGCSE Environmental Management is really marked
IGCSE Environmental Management runs across six papers (11, 12, 13, 21, 22, 23), and in our bank the marking is dominated by point-marked questions: 1,000 of the 1,116 questions we hold are point-marked, against 101 calculation questions and just 15 pure-levels questions. That means the large majority of marks are for stating, identifying or describing a specific creditable fact or reason listed on the mark scheme, not for building an argument.
The calculation element sits mainly in the data-response papers (21, 22, 23), where you read a graph, table or diagram and work out a value — population size, a rate, a temperature range. These marks reward correct working as much as the right number, but there's no partial credit for a vague answer with the right idea; the mark scheme wants a specific figure or a named process.
The small pure-levels component (15 questions across the bank) shows up as an evaluative or extended-writing task, often asking you to weigh up a resource conflict or an environmental trade-off. Here the examiner is not counting points but judging whether your answer is balanced and supported by evidence — a strong opinion with no data behind it will not do well, even if it is well written.
Because points so heavily outweigh levels, the single most reliable skill in this subject is precision: naming the right substance, quoting the right unit, reading the right value off a graph. Vague or approximately-right answers lose marks that a more exact answer would keep.
Where candidates actually lose marks
- On population pyramid questions, candidates explain why males die earlier instead of giving the actual reason asked for — that females live longer and so outnumber males in the oldest age group. (try the question)
- Asked what 'pregnancy is wanted' means, candidates write about hospitals, financial support for parents or pro-natalist policy instead of addressing planned/intended pregnancy directly. (try the question)
- On a nutrient-cycle question, candidates name 'phosphorous' when the mark scheme requires the specific term 'phosphate'. (try the question)
- Bar chart construction loses marks for not labelling both axes, drawing bars of uneven width, plotting a line graph instead of a bar chart, or using pen. (try the question)
- Candidates describe a lack of rain drying out soils but fail to make the connecting point that lighter, drier soils are more prone to erosion — the answer stops one step short of the mark. (try the question)
- On biological control, candidates write that it means 'not using chemicals' or that it is 'a natural method' without ever mentioning the use of a predator, which is the point actually being credited. (try the question)
- On evaluate-style questions about fish stock decline, candidates often omit overfishing (a main cause), suggest that cleaning fish would remove pollution (it won't remove plastics or heavy metals), or spend the answer on oil-spill clean-up without weighing evidence on both sides. (try the question)
- Asked to describe a population pyramid, weaker answers analyse individual bars one by one, or simply say 'it's a pyramid shape', instead of describing the overall shape the question is asking for. (try the question)
Command words in IGCSE Environmental Management
| Command word | Times in our bank | What it demands |
|---|---|---|
| Suggest | 286 | Asks for a plausible, reasoned idea rather than a single memorised fact — you need to propose something sensible and, where marks allow, briefly justify it. |
| State | 261 | Wants a short, exact fact or figure with no explanation attached — extra detail earns nothing extra, but a vague or general answer earns nothing at all. |
| Describe | 140 | Requires you to characterise a pattern, process or feature in enough specific detail that someone could recognise it — naming it alone is not enough. |
| Explain | 119 | Needs a reason or mechanism linking cause to effect, not just a restated fact; the mark is for the 'because', not the 'what'. |
| Calculate | 80 | Marks are for a correct numerical answer, usually with working shown, drawn from data given in a graph, table or diagram in the question. |
| Complete | 60 | Used for finishing a diagram, table, graph or pyramid accurately — the mark is for getting the missing element precisely right, not roughly right. |
| Plot | 21 | Requires accurate placement of data points or bars on a grid, with correct axes, scale and labelling — technique errors here lose marks even when the underlying idea is correct. |
| Name | 21 | Wants the specific, correct term for a substance, process or feature — a near-miss or general category answer will not be credited. |
How to revise with past papers
Because this subject is overwhelmingly point-marked, the most useful thing past-paper practice can do is train you to spot exactly which fact, term or figure a question wants — and to give it precisely, without padding. When you check your answer against a mark scheme, don't just ask 'was I roughly right'; ask which specific word or number the mark was actually for.
For the calculation and data-response questions, practise reading graphs and tables under timed conditions and always show your working — a correct method with a small arithmetic slip is worth checking against real mark schemes, since method marks are often available even when a final figure is off.
For the handful of evaluative, levels-marked questions, practise building a two-sided answer with evidence on each side before you reach a judgement — read a few real answers on these topics to see what a balanced, evidence-based response looks like compared with a one-sided opinion.

Is Environmental Management mostly about learning facts?
Largely, yes. In our bank, 1,000 of 1,116 questions are point-marked, so precise recall of terms, processes and figures is what earns most marks — though a smaller set of calculation and evaluative questions also appears.
Do I need to show working for the calculation questions?
Yes. Showing your working means an examiner can follow your method even if the final figure is slightly wrong, and it is generally good exam practice across subjects with calculation elements.
What's different about the evaluative questions?
These are the pure-levels questions in the subject — a small minority overall — and they're judged on the balance and evidence of your argument, not on how many separate points you list.
Which topic areas come up most in past papers?
In our bank, the atmosphere and human activities, human population, and rocks/minerals/the lithosphere are the most frequent topics, followed by natural ecosystems and oceans and fisheries.
