What is Exam Stress and How to Prevent It

Q: Why do students who know the material still fail to get top marks?

This happens due to an execution gap, where a student understands the concept but does not phrase their answer according to the strict examiner mark scheme. Sharpening your exam technique, decoding question command words, and practising past papers secures top grades.

International curricula like the IB, British, and US programmes carry a high workload. Combined with sports and extracurriculars, panic and stress quickly build up as exams approach.

How you study can break the exam stress.

We sat down with Nicola van Heerden, Academic Success Manager at LearnFire, to get her take on exam stress and what you can do to prevent it.

“Achieving a 5 in Computer Science has been an important milestone for our son, and we’re very pleased with the progress he has made through LearnFire’s academic support. LearnFire's strategic and personalised approach has helped him think more logically and apply core programming and computational concepts with greater accuracy in assessments.” ~ Brigit M. 2026 Google Reviews

Question 1: So Nicola, let’s start at the beginning. What is exam stress?

Nicola: Exam stress is a psychological and physical response when upcoming exams leave a student feeling unprepared or overwhelmed. Students react differently:

some feel ill,
cannot sleep,
develop stomach conditions,
withdraw from family and friends, and lose interest in their usual activities.

Question 2: Why does exam stress develop?

Nicola: Modern society values academic results highly, causing students to tie their self-worth to grades. We speak to all kinds of students across a whole range of grades, and we find that even top performers experience exam anxiety. They learned to manage it more effectively.

Data from the OECD shows that 55% of students report high anxiety over testing, even when thoroughly prepared. When more than half of the prepared students experience this anxiety, it is not their work ethic that we should question.

We must look at classroom support, time management, planning, workload and the balance between memorisation and comprehension.

There are signs of exam anxiety. You can look for the following:

Fear of failure: Overthinking, physical tension
Low self-esteem: negative self talk, withdrawal
Chronic stress: Sleep disturbances, irritability, forgetfulness
Fear of the unknown: Loneliness, social anxiety, dizziness, nausea and other signs of illness before school start
Displacement: Hyper-Vigilance, tantrums, illness avoiding school, detachment
Other hidden factors: If you are wondering how to help a teenager who is crying over schoolwork, the first step is to ask them:

I’ve noticed you seem a bit overwhelmed lately? How can we tackle this workload together?

Exam Anxiety: The Reality

55% of students experience severe anxiety even when they are fully prepared.

This means over half of your child's peer group is battling internal panic, regardless of how many hours they spent studying the night before.

55.6% of students in advanced academic tracks suffer from maladaptive perfectionism.

Passing is not the goal. Elite students are terrified of missing their top-tier university goals, which affects their performance.

Up to 22% of secondary school students have their final grades actively suppressed by test anxiety.

This is the difference between an IB 7 and a 5, or an A* and a B, purely due to stress rather than a lack of knowledge.

Question 3: Students study all the time, surely they will be prepared by exam time?

Nicola: More hours do not equal better results. A student retains very little after a four-hour study marathon.

I frequently speak to students who have spent an entire afternoon studying but still feel unprepared because they focused on memorising instead of applying the work.

For example, IB Chemistry, requires deep conceptual understanding, not just memorised formulas. In the exam, students must apply these formulas to unfamiliar, real-life scenarios to prove they understand the underlying science.

Students can only bridge the gap between theory and practice by tackling mock exams and past papers. They must also get to grips with the mark schemes to understand what the examiners require.

Examiners sometimes look for specific wording and terminology, and the student needs to know which wording and phrases to use when answering questions.

Exam prep takes time. We recommend a 12-month preparation window because curricula like IGCSEs and the IB contain a massive volume of content.

Students must learn to manage their time, deconstruct the syllabus into manageable blocks, and understand each block ahead of their schedule. This leaves enough time to ask for support when they missed a concept.

Preparation over time builds confidence. Once a student gains confidence, their anxiety becomes manageable. This keeps them calm in the exam room, allowing them to use the critical thinking skills they need to solve complex problems.

Ultimately, the number of hours spent studying matters less than how productively a student uses that time. Our career educators and academic coaches frequently give students their weekends back simply by organising and managing their schedules efficiently.

Question 4: What should parents and students dealing with exam stress do?

Nicola: Finding a study rhythm that suits your child can ease some of the pressure. While every student is unique, here are a few starting points, backed by research, to help your child find the study skills technique that works best for them

Spacing effect: Start revision early and allow at least 12 months to prepare. We suggest you take a look at micro-learning. It breaks complex topics into short, media-rich lessons. This prevents cognitive fatigue and dramatically improves long-term information retention. (Shail, M. S., 2019)

Interval studying: Study for 25 minutes, then take a 5-minute break. After four blocks, take a 30-minute break to do something completely different. Take a walk around the block and avoid your smartphone. The Pomodoro technique manages mental exhaustion, increases productivity and prevents burnout.

Use revision guides: Revision guides are mostly written by curriculum creators. It’s worth working with the revision guides because:

It covers the whole course: They summarise the entire official syllabus, ensuring no major topics are missed.
It is highly reliable: They offer highly accurate information perfectly aligned with the exam.
It contains "nothing more, nothing less": Textbooks include background context and long explanations to introduce a concept. Revision guides cut the fluff, providing only the bare-minimum facts, definitions and formulas you need to pass. Use it to focus on what is important.

Question 5: Where does LearnFire fit into exam preparation?

In Conclusion: When you are preparing for big exams like the IB, IGCSEs, or A-Levels, standard resources only take you halfway:

The textbook teaches the subject from scratch.
The revision guide provides a quick reminder of the facts.

LearnFire bridges the gap between knowing the content and using it in an exam. Many students understand the work but struggle to apply it under pressure. We focus on time management, answer structure, exam techniques and preparing students to approach their exams with confidence.

"Best time and money investment in my child's education. Private tutoring with the experts. Our previous experience was with just graduated older kids that were as lost as our child, a waste of time and frustrating. We found Learn Fire, and the experience was great from the beginning. Thank you." ~ M. Candia 2024,TrustPilot review
