Five Final-Month OC Mistakes That Undo Months of Prep (2026)

You've done the work. The thinking-skills papers, the reading comprehension drills, the Saturday mornings at the kitchen table. And now, with five weeks left before the July OC test, a quiet fear is creeping in: am I about to ruin it?

Not because you've slacked off. Because you're paying attention — and that's when parents tend to make their worst decisions.

Here are the five final-month mistakes I see most often, and what to do instead.

Switching to a new resource at the last minute

There's always a parent in a Facebook group who swears by a paper set you haven't tried yet. Five weeks out is not the time to find out. Your child has built familiarity with a particular style of question — switching now means re-learning format and language, not practising skills.

What to do instead: Finish what you started. If you've been using one set of practice papers, stay with them. Consistency compounds.

Doubling the workload to get ahead

The test is close and the pressure feels real. So you add another session. Then another. By week four, your child is doing two hours a day, dinner-table maths, and car-trip quiz questions.

The research on cognitive load is clear: tired kids don't consolidate well, and stressed kids don't problem-solve well. The OC Thinking section in particular requires the kind of flexible reasoning that shuts down under pressure.

What to do instead: Cap at 45–60 minutes of focused practice per day and hold that line. Protect sleep — it's where memory consolidation actually happens.

Treating every practice score as a verdict

"She only got 68% on the thinking section — is that going to be a problem?"

Practice papers are diagnostic tools, not predictions. The scoring on commercial papers varies widely from year to year and from one publisher to the next. A 68% today doesn't tell you what the test-day score will be.

What to do instead: Use scores to identify question types to revisit, not to calibrate panic. "What type of question caught her out?" is the useful question. "Is 68% good enough?" is not.

Catastrophising in earshot

This one is hard to admit. A parent mentions to their partner — over dinner, thinking the kids aren't listening — that "if he doesn't get in, we'll have to rethink the whole plan." The kid hears it.

Primary school children are excellent at absorbing parental anxiety and terrible at processing it. They don't understand what "rethink the plan" means, but they understand that the stakes are high and that failure has consequences.

What to do instead: Keep your worry conversations out of earshot. What children need to hear, repeatedly and genuinely, is that you're proud of the work they've done — not just the outcome they're aimed at.

Skipping the logistics conversation

Parents spend months on content and twenty minutes on logistics. Then the kid arrives at the test centre anxious about where to sit, what happens if they need to go to the bathroom, or whether scrap paper is allowed.

Test-day uncertainty is its own kind of cognitive load.

What to do instead: About a week before the test, walk through the practical details together. What time you'll leave. What they'll eat. That it's fine to skip a question and come back. That you'll be right there when it's done. Not as a pep talk — as matter-of-fact logistics. It removes a layer of unknowns on the day.

What ties all five together

Every mistake on this list comes from the same source: converting what should be a long-horizon skill-building effort into a high-stakes performance event in the final stretch.

The families who tend to do well in the last few weeks aren't the ones who worked hardest in the final month. They're the ones who kept the preparation atmosphere steady — practice as routine, not as emergency.

If your child has been working consistently through Term 2, the most valuable thing you can do now is not add more. Keep the sessions, keep the rhythm, and take the pressure off the scoreboard.
