Maths anxiety and the exam: what actually helps

5 min read

Maths anxiety is not the same as being weak at maths. It occupies the mental workspace multi-step problems depend on, and several tested interventions reduce its cost.

Anxiety is not the same as ability

A student who can solve a question calmly at the kitchen table and cannot solve it in an exam hall has not forgotten the maths. Something is competing for the resources the maths needs. Treating that as a gap in ability leads to more of the revision that was never the problem.

What anxiety actually costs

Ashcraft and Krause (2007) set out the mechanism clearly: maths anxiety consumes working memory, the limited mental workspace used to hold intermediate steps while solving a problem. Because the workspace is finite, anxious thoughts and problem-solving are in direct competition.

This predicts something specific and important. Anxiety costs least on simple recall and most on multi-step problems that demand holding several things in mind at once, which is precisely where GCSE, IGCSE, IB and A-Level marks are concentrated. The harder the question, the more anxiety takes.

Three things with evidence behind them

First, writing about the worry. Ramirez and Beilock (2011), published in Science, had students spend about ten minutes before an exam writing freely about their thoughts and feelings regarding the test. Those students scored significantly higher than a control group, and the benefit was largest for the most test-anxious students. The plausible reading is that offloading the worry onto paper frees the working memory it was occupying.

Second, reinterpreting the physical symptoms. Jamieson and colleagues (2010) found that telling students that exam arousal, the racing heart and tight stomach, can aid performance rather than signal impending failure improved their scores. The sensations do not have to be removed, only read differently.

Third, reducing the load the exam places on working memory in the first place. Fluency with the underlying steps, such as manipulating fractions, rearranging expressions and recalling standard results without deliberation, leaves more capacity for the actual problem. This is the practical upshot of cognitive load research going back to Sweller and Cooper (1985): automaticity in the basics is not busywork, it is what makes hard questions tractable.

A note for parents

Maloney and colleagues (2015) found that when parents who were themselves anxious about maths frequently helped with maths homework, their children learned less maths across the year and became more maths-anxious. When those parents helped rarely, the effect was not present. Anxiety is transmissible, and often through the phrase 'I was never any good at maths either', offered kindly.

The useful adjustment is small: keep homework help calm and factual, avoid framing maths ability as a fixed family trait, and hand over the explaining when it starts to generate friction.

What to do in the fortnight before a paper

• Sit full papers under real conditions: timed, no notes, no phone. Familiarity removes one source of novelty on the day.
• Spend ten minutes writing out exam worries the day before or shortly before the paper.
• Drill the underlying fluency so that routine steps cost no thought.
• Reframe nerves as the body preparing rather than as evidence of impending failure.
• Protect sleep in the final week ahead of extra revision hours. Working memory degrades quickly without it.
