Four Weeks to the OC Test: What You Can Still Change — and What You Can't
Four weeks from the OC test, the gap between what can be improved and what can't matters more than how hard you push.
27 June 2026 · Joey67 Team
Your child has four weeks left before the OC test. You've done the work — the past papers, the weekly sessions, possibly the tutoring. But now you're asking yourself whether to push harder, and if so, where.
Here's the uncomfortable truth most prep guides won't say: at four weeks out, not everything is still moveable. Some things that matter for OC scores were shaped by years of reading, play and classroom experience. No amount of drilling changes them in a month.
That doesn't mean this stretch is useless — far from it. It means where you focus now is everything.
What Won't Move Much in the Final Month
This isn't pessimism, it's calibration.
Reading comprehension depth — your child's ability to grasp the meaning behind a difficult passage — reflects years of reading. If they're a strong reader, you'll see that in their comprehension scores. If they're not, drilling another twelve practice passages in June won't fundamentally shift it.
Processing speed — how fast they can mentally juggle information — is relatively stable at this age and doesn't respond quickly to targeted practice.
Broad vocabulary — the words they know and can use confidently. Vocabulary grows over years of exposure, not weeks of word lists.
Mathematical intuition — number sense, the ability to spot shortcuts or approximate quickly — develops over time. You can help them recognise a pattern they've seen before; you can't build intuition from scratch.
Understanding this matters because it tells you what not to do: don't spend these four weeks furiously cramming the skills that were always going to be fixed by this point. That's the mistake that leads to burnout in the final stretch.
What Can Still Move — and Moves Quickly
Here's what the final four weeks are actually good for.
Test-taking strategy. Many children, even capable ones, misallocate time during the actual test. They spend six minutes on one hard thinking-skills question when they could have banked five easier ones first. This is a trainable habit and four weeks is plenty of time to build it.
Careless errors. Re-reading the question before answering, circling key words, checking calculation steps — these are process habits that can be installed fairly quickly with deliberate practice. For some kids, fixing this alone moves their score noticeably.
OC question-format familiarity. The OC thinking-skills and reading sections have recognisable question types: analogy sequences, odd-one-out patterns, inference questions, vocabulary-in-context. Kids who've seen enough of each type stop losing time to confusion about what's actually being asked.
Regulation under pressure. A child who freezes when they hit a hard question will throw away marks that were never actually lost. Practising the simple act of skipping and returning — timed, with a little pressure — is a concrete skill that responds quickly to practice.
Confidence in a weak spot. If maths is strong but thinking skills feel shaky, four weeks of targeted thinking-skills work will move the needle. Focused beats broad at this stage.
Where Most Parents Go Wrong Right Now
The pattern that comes up most often: parents ramp up comprehension passages because reading feels improvable and passages feel concrete. But if their child is already performing adequately in reading, the points are almost always being dropped somewhere else — time management, misread question stems, questions skipped and never returned to.
The same applies to maths. More calculation drills feel productive. But if the calculation is already solid, the gap is likely in multi-step word problems where it's the reading comprehension requirement that's actually tripping them up.
Before adding practice volume, sit with your child's last marked test and look at where the marks went. A test with errors categorised by type tells you far more than gut feel does.
A Practical Frame for the Next Four Weeks
Don't try to lift everything. Pick two areas from the list above — both from the "can still move" column — and be deliberate about them.
If you're doing 30-minute sessions, try splitting them: fifteen minutes on timed past-paper questions targeting the specific question-type your child finds hardest, and fifteen minutes reviewing their errors with them rather than for them. The conversation about why they chose a wrong answer is worth more than the volume of questions completed.
Ease off the week before the test. By then the work is done. What helps most in that final stretch is sleep, routine and a child who doesn't feel wrung out.
What to Do This Weekend
Pull out your child's last two or three practice results. Mark every wrong answer with a label: time ran out, misread the question, concept gap, careless slip. Tally each category.
That tally is your prep plan for the next four weeks. Work on what the data points to, not what your instinct says feels most urgent.
If you want a low-friction way to add daily practice without a full sit-down session, joey67's OC thinking-skills and maths sets are short enough to fit in fifteen minutes and targeted enough to cover the question patterns that actually appear in the test. The goal for the next four weeks isn't more volume — it's the right kind of work, done calmly and consistently.
Four weeks is enough time to move the things that can still move. Don't spend it on the ones that can't.
