Self-marking is only useful if it matches how the paper is actually marked. Generous self-marking is the commonest reason a student is surprised by their result.
The problem with generous marking
Students routinely award themselves the mark for “I knew that, I just wrote it wrong”, or for an answer with no working where working carried the marks.
The result is a practice score that has no relationship to the exam score, and a student who believes they are ready when they are not.
Marking as a marker would
No mark for an unsupported answer where method carries credit. No mark for an answer without units where the unit was required. No mark for the right value against the wrong part.
Equally, credit for correct method even where the final answer is wrong. Students routinely under-award themselves here, and it matters, because it tells them their approach was sound.
Rules for honest self-marking:
- No credit for unsupported answers where method is required
- No credit for a missing or wrong unit
- Full credit for sound method with a wrong final answer
- Record the cause of every lost mark
- Mark a day later, not immediately
Recording the cause, not just the mark
Beside every lost mark, write why: reading, method, execution or presentation. The score is nearly useless; the causes are the whole point.
After a few papers the pattern is visible and narrow, and it becomes the revision plan.
Making it bearable
Strict marking is discouraging if the score is the focus. Shifting the focus to the causes makes it constructive, because causes are fixable in a way that a percentage is not.
It also helps to mark a paper the day after sitting it rather than immediately, when the memory of intending the right thing is strongest.
One more thing makes strict marking sustainable: separate the marking from the review. Mark the paper coldly, put it aside, and work through the causes in a second sitting. Doing both at once turns every disputed mark into an argument, whereas splitting them keeps the scoring impersonal and leaves the useful conversation for when nobody is defending anything.
What lessons at Odyssey are actually like
One of our students, unscripted, on how the lessons run. Secondary level in this clip; the same method underlies the primary classes. More are on Odyssey Math TV.
Where Odyssey fits
We mark for method in class and discuss the working rather than the total, so students learn what actually earns credit.
We teach maths only, in small classes at Hexacube, 160 Changi Road #01-02, about three minutes from Eunos MRT. See the primary and secondary programmes, our MOE-aligned curriculum, schedules and fees, or the tutors who teach. Free video solutions to past-year papers are on Odyssey Math TV.
Almost every primary topic is scaffolding for a later one, and the scaffolding is invisible until it gives way. That is why our curriculum is written across all six years, Primary 1 to Primary 6, rather than level by level — it lets us see the whole structure a child is standing on, not just the step they are currently on.
If you are unsure whether tuition is the right answer yet, the free trial is a reasonable way to find out without committing to anything. We will give you an honest read on where your child stands and what would actually help. Book a free trial class or WhatsApp +65 8512 6882.
What we describe here comes from teaching this syllabus in our own classes since 2012. It is not a forecast for any individual child: progress is produced jointly, by a student willing to do the work with support at home. We do not promise grades. Topics follow the MOE primary mathematics syllabus — check the current syllabus on the MOE website for the definitive version, and see our curriculum page for how we teach it.
Frequently asked questions
Should my child mark their own work?
Yes, provided the marking is strict. Self-marking is valuable; generous self-marking is worse than not marking at all.
Should credit be given for correct method with a wrong answer?
Yes. That is how the paper is marked, and students routinely under-credit themselves here.
Why mark a day later?
Because immediately afterwards a student remembers what they meant to write, which makes honest marking much harder.
What matters more than the score?
The cause of each lost mark. Reading, method, execution and presentation need completely different remedies.
