Most parents I speak to make the same mistake in the first six months of 11 plus prep. They focus on whether their child can answer the questions. They check the answers, mark the paper, work through the wrong ones together. The clock is an afterthought. They get to it later, once the basics are solid.
That's backwards. The 11 plus isn't measuring whether your child knows how to solve a number sequence question. It's measuring whether they can solve 50 of them in 50 minutes. The clock ticks down. The kid next to them is breathing fast. Speed under pressure is the test. Skip that, and you're prepping for a different exam.
What timed practice actually does
When a child works untimed, their brain has the luxury of scanning the question, considering the options, checking the working twice, and only then committing. That's a lovely way to learn. It's a terrible way to prepare for an exam where the average GL Assessment maths paper gives them less than 60 seconds per question.
Timed practice rewires three things at once. The first is recall speed. Mental maths under time pressure stops being a thinking task and becomes a reflex. Second is decision-making. When the timer is running, your child stops agonising over whether to skip a question. They just do it. Third, and the bit nobody talks about, is the physical experience of pressure. The dry mouth, the racing pulse, the tunnel vision when something hard appears at question 23. Those things only get manageable through repeated exposure.
You can't teach that on the sofa with a cuppa.
The "I knew that one" problem
Every parent has had this conversation after a mock test. The child comes home, you go through the paper, and they say "I knew the answer to that one, I just ran out of time." It feels like a near miss. It isn't. It's a structural problem.
If a child can solve a question untimed but not timed, they don't really have the question yet. They have the method but not the speed. Speed only comes from repetition under the same conditions they'll face on the day. Doing a paper without a clock isn't half practice. It's a different activity.
The fix is simple. From around six months out, every practice paper your child sits should have a real timer running. Phone timer, kitchen timer, whatever. Visible to them, ticking down. They learn to glance at it without panicking. They learn what 25 minutes feels like. That sense of pace is what separates a kid who finishes the paper from one who runs out of time on the last 12 questions.
When to start timing, and how strict to be
There's a balance here. Slap a 50-minute timer on a Year 4 child who's never seen a verbal reasoning paper. You'll create the exact anxiety you're trying to avoid. Wait until two weeks before the exam to introduce timing and you'll panic them at the worst possible moment.
The middle ground I'd suggest looks like this. In the first three months of prep, work untimed. Build the foundations. Make sure they understand how to approach each question type. Then introduce loose timing, say, give them 20 percent more time than the real paper allows. So a 50-minute paper gets 60 minutes. They feel the clock without being crushed by it.
Three months out from the exam, switch to real exam timing. By this point your child should be able to handle a full paper at proper pace without falling apart. Two months out, start running mock conditions. One paper a week, no breaks, no parent intervention, no checking answers until the timer ends. Cold and uncomfortable, but it's the only way to build the stamina the actual exam demands.
The pacing skill nobody teaches
Here's the bit most prep books skip. Pacing is a skill, and it's separate from knowing the content. A child who can do every question on a paper but can't manage their time across 50 minutes will still come out below the pass mark. Why? Because they spent 11 minutes on a hard question early on and then had to rush the last section.
Teach your child to break the paper into chunks in their head. On a 50-minute paper, that might be 15 minutes for the first third, 20 for the middle, 15 for the final third. Mark the times on a watch face if they're allowed one. The point isn't precision. It's awareness. A child who notices at the 25-minute mark that they're only on question 18 can speed up. A child with no internal clock can't.
This is the hardest thing to teach because it feels abstract until you've done it. The answer is just doing it, again and again, until it becomes automatic.
What to do when timing exposes a problem
Sometimes a parent times their child for the first time and the result is grim. The child finishes 35 of 50 questions, panics, and bursts into tears. What now?
Don't drop the timer. The timer isn't the problem. The problem is your child has been practising for accuracy. Now they need to practise for speed. Those are different muscles. The shock comes from discovering they aren't the same.
Drop the difficulty for a week. Use papers that are slightly below the level they've been working on. Time them. Let them finish a few timed papers comfortably to build the feeling of "I can do this in the time." Then ratchet the difficulty back up while keeping the timer in place. The confidence has to come from completing timed papers, not from completing easy untimed ones.
If you're in Buckinghamshire prepping for super-selective grammars, this matters even more. Those exams have brutal time pressure built into the paper design. A child who hasn't done dozens of fully timed practice papers will struggle on the day, no matter how clever they are.
Don't time everything though
One more thing. Not every session needs a timer. Skill building still happens slowly. When your child is learning a new question type for the first time, say they've just hit cube nets in non-verbal reasoning, let them work through five or six examples without time pressure. Get the method right first. Then add the clock once the technique is solid.
The mistake is not having a timer at all in the lead-up to the exam. The other mistake is timing everything from day one. Both are common. Both produce the same outcome. A child who underperforms relative to their ability.
What "good" timed performance looks like
In the final two months, your child should be finishing full practice papers within the time limit, with maybe one or two questions left blank because they got skipped. They should know which questions are theirs to nail and which they'll guess and move on from. They should be able to glance at a timer at the 30-minute mark and adjust pace without panicking.
That's the target. It takes weeks of practice. You can't cram it in the last fortnight, no matter how many extra papers you buy.

FAQs
How early should I start timing my child's practice papers?
Six months out, with extra time on the clock. Three months out, switch to real exam timing. Two months out, run weekly mocks under proper conditions. Don't introduce the timer in the final fortnight. That creates panic, not preparedness.
My child can do the papers but not in time. Is that a real problem?
Yes. The 11 plus is a speed test as much as a knowledge test. Knowing the answer doesn't help if the bell rings before they get there. Practise timed papers regularly so speed catches up with accuracy.
Should I time my child during early prep when they're still learning a question type?
No, not for new question types. Let them learn the method untimed first. Once the technique is solid, layer the timer back in. Timing a child who hasn't yet learned how to do a question only teaches them to feel rushed and confused.
What if timed practice makes my child anxious?
Build up gradually. Start with shorter sections rather than full papers. Use easier material so they get the win of finishing within time. Once the feeling of "I can finish in the time" is established, the anxiety usually drops. If it doesn't, that's worth a separate conversation about exam stress before you push harder on timing.
