How IGCSE Additional Maths (0606) is really marked
In our bank, IGCSE Additional Mathematics runs across six papers (11, 12, 13, 21, 22, 23), and marking splits between calculation-style method marking and points marking: 269 questions in our bank are calculation questions, where method and final answer both carry marks, against 433 points questions, where a mark is awarded for reaching a specific creditable stage or stating a specific result. Papers 21–23 lean more heavily on calculation (48–55 calculation questions each) than papers 11–13 (35–39 each).
Because the calculation questions carry method marks, correct working that leads to a wrong final answer can still earn most of the marks available — but the reverse is also true: a correct final answer with no working shown, or working that skips a required step, is not credited, because the mark scheme is checking the method itself, not just the destination.
The points questions in this subject are typically the smaller, sharper steps within a longer calculus, vectors or algebra problem — substituting the right value, stating the right form of an inequality, rejecting an invalid root — so precision at each individual step matters as much as the overall strategy.
Where candidates actually lose marks
- Not showing the substitution step explicitly in a calculation — for example substituting a value into a derivative without writing that substitution out, so a correct final method cannot be inferred from an unsupported number. (try the question)
- Using an unsimplified or wrong variable in a sequence problem — for example using the first term alone where the first term plus the common difference was needed, which throws off every subsequent expression. (try the question)
- Solving a modulus inequality by manipulating the equations algebraically only, rather than using the graph as the question required, or stating an inequality the wrong way round. (try the question)
- In vector geometry, stating only one of two required expressions for a position vector, using the same scalar for two different unknowns, or leaving vector equations unsimplified before trying to equate them. (try the question)
- Reaching a numerical value from incorrect working and stating it as the final answer — since all working must be shown, a correct-looking answer arrived at through a flawed method earns no credit. (try the question)
- Substituting the wrong value when testing whether a given linear expression is a factor of a polynomial, or stating the result of the substitution without showing the calculation that produced it. (try the question)
Command words in IGCSE Mathematics - Additional
| Command word | Times in our bank | What it demands |
|---|---|---|
| Find | 525 | By far the most common instruction — asks for a specific value, expression or set of coordinates, with the method usually needing to be shown for the marks to be awarded. |
| Deduce | 55 | Asks you to use a previous result or given information to reach a further conclusion without redoing the whole calculation from scratch. |
| Draw | 41 | Used for sketching graphs and curves — correct shape, key features (asymptotes, intercepts) and transformations of a related function are what earn the mark. |
| State | 27 | Wants a brief, exact result — a domain, a condition or a value — without further working, once it has been established. |
| Express | 18 | Requires rewriting an expression in a specified form (for example a given algebraic structure), so matching that exact form matters as much as the algebra being correct. |
| Show | 12 | Demands a fully justified chain of reasoning to a given result — every step must be present, since the answer itself is already known. |
| Solve | 7 | Asks for the value or values that satisfy an equation or inequality, typically with all valid solutions and rejection of invalid ones. |
| Explain | 7 | Wants a reasoned justification — for example why a solution should be rejected or why a discriminant condition applies — rather than just a numerical result. |
How to revise with past papers
Because so much of this subject's marking is method-based, the most valuable revision habit is writing out full working every time, even in questions you can do in your head. This subject's calculation questions credit the method itself, so an answer with no supporting steps is treated the same as no attempt at all if it's wrong, and full working protects marks even when the final figure is off.
Practise the connecting steps between stages of a longer problem, not just the individual techniques. Many of the mistakes that lose marks in this subject happen at transition points — substituting into the wrong expression, forgetting to reject an invalid root, or not linking one part's result into the next part — rather than in the core calculus, algebra or trigonometry itself.
When you check your own answers, don't stop once the number matches the mark scheme. Check whether your method matched what was required (for example, whether a question asking you to verify a value expected exactly that, rather than a longer derivation) — this subject rewards using the specific method the question calls for, not just any method that gets to the right place.

Is Additional Maths marked more like a calculation paper or a points paper?
Both, in a genuine mix: in our bank 433 questions are points-marked and 269 are calculation-marked, with calculation questions more concentrated on papers 21–23 than on 11–13.
Can I get credit for a wrong final answer?
In the calculation questions, yes — method marks are available for correct working even if the final answer is wrong, provided the working is actually shown, since a correct-looking answer with no working or with incorrect working underneath is not credited.
What is the most frequent command word in this subject?
Find, used 525 times in our bank — far more often than any other command word, reflecting how much of the paper asks for a specific value or expression to be obtained.
Are there any extended, level-marked questions in this subject?
No — in our bank every question is either points-marked or calculation-marked; there is no pure-levels or points-with-levels marking in Additional Mathematics.
