A teacher’s guide to calming your mind, improving focus, and performing better—based on real neuroscience.

I’ve seen it countless times—as a student myself, and now as an educator guiding hundreds of students through some of the most stressful exam seasons of their lives.

One of my students, Aanya, used to break down the night before every major test—even though she was one of the best-prepared in the class. Another, Sahil, would go completely blank in the middle of the paper, despite scoring well in mock tests.

What these students were experiencing wasn’t poor preparation—it was exam anxiety. And in today’s hypercompetitive world, staying calm during exams is no longer a soft skill—it’s a core performance strategy.

The good news? Science has a lot to say about staying calm under pressure. And today, I’m going to walk you through the best science-backed techniques I’ve used myself and taught others—to help you not just survive exams, but walk in with confidence and clarity.

🧠 What Happens to the Brain Under Exam Stress?

Let’s start with the biology of stress.

When you’re anxious, your brain’s amygdala kicks in—triggering a fight-or-flight response. This floods your body with cortisol, a stress hormone. In the short term, cortisol helps you stay alert. But too much of it:

• Impairs short-term memory
• Narrows attention
• Disrupts logical thinking

🧬 According to a 2021 study in Neuroscience & Biobehavioral Reviews, chronic stress reduces activity in the prefrontal cortex, the part responsible for focus and problem-solving [source].

Translation? You may know the answers, but your brain can’t access them if it’s panicking.

That’s why staying calm isn’t just about “feeling good.” It’s about unlocking the brainpower you already have.

✅ 1. Rewire Your Self-Talk (Cognitive Reappraisal)

When students tell me “Sir, I’m going to fail,” I pause them immediately.

How you talk to yourself affects your brain’s chemistry.

Cognitive reappraisal is a psychological technique where you reframe your thoughts. Instead of:

• “I’m so stressed, I can’t handle this,” try → “I’m feeling pressure because this matters to me—and I’m prepared.”
• “What if I forget everything?” becomes → “Even if I forget one thing, I’ve got the rest covered.”

🧠 A study in Psychological Science found that reframing anxiety as excitement improves performance under pressure [source].

✍ My Tip:

Before your exam, write down 3 things you’ve done well in your prep. Read it aloud. Repeat positive self-talk while walking into the exam hall.

✅ 2. Practice “Power Postures” for 2 Minutes

Sounds silly—but hear me out.

Standing tall with your chest open and arms out (think superhero pose) increases testosterone and decreases cortisol, giving you a mental edge.

🧬 Harvard social psychologist Amy Cuddy’s famous study (2010) showed that body language directly affects stress hormones and performance [source].

🧍 Try This:

Before entering the exam room, find a quiet spot (even in the washroom if needed) and hold a confident posture for 2 minutes. Breathe deeply. Your brain will follow your body’s cues.

✅ 3. Use a 4-7-8 Breathing Pattern to Calm Your Nerves

This technique has helped countless students in the minutes before the bell rings.

How it works:

• Inhale through your nose for 4 seconds
• Hold for 7 seconds
• Exhale through your mouth for 8 seconds

Repeat 3–5 times.

This stimulates your parasympathetic nervous system, slowing heart rate and calming the mind.

🧘‍♂️ A study published in Frontiers in Human Neuroscience found that slow breathing techniques reduce anxiety and enhance focus [source].

✅ 4. Chew Gum (Yes, Seriously)

Chewing gum may seem trivial—but research shows it can reduce stress and improve attention.

🧪 A 2015 study in Nutritional Neuroscience found that students who chewed gum before exams had lower anxiety and improved memory recall [source].

🍬 Try:

Sugar-free mint gum right before the exam. It acts as a sensory distraction and increases blood flow to the brain.

✅ 5. Listen to Music Before, Not During

Music has a powerful effect on mood. But listening during the exam may divide your attention.

Instead, use music before the exam to relax.

🎧 Recommended:

• Lo-fi beats
• Nature sounds
• Classical music (like Mozart)
• Instrumental movie soundtracks

🎶 A 2020 meta-analysis in Health Psychology Review confirmed that music reduces pre-performance stress when used before high-stakes tasks [source].

✅ 6. Journal for 10 Minutes the Night Before

When your mind is racing, write it out.

Studies show that journaling about your worries the night before an exam helps “clear the mental clutter” and reduces pre-exam anxiety.

✍ A study in Science found that students who wrote about their fears 10 minutes before an exam scored higher than those who didn’t [source].

My Tip:

Use a notebook. Start with: “What’s stressing me right now?” Let it flow. Then close the book and sleep.

✅ 7. Plan a “Worry Window” During Study Breaks

You can’t stop anxiety by pretending it doesn’t exist. But you can contain it.

Set a 15-minute window during the day to allow yourself to worry. Outside that time, gently say: “I’ll think about this during my worry time.”

📌 Used in cognitive behavioral therapy (CBT), this technique reduces intrusive thoughts and improves concentration [source].

✅ 8. Eat a “Brain-Calm” Breakfast

Avoid heavy carbs or sugar. Your brain needs slow-burning fuel on exam day.

🥣 Ideal breakfast:

• Oatmeal + banana
• Eggs + whole grain toast
• Almonds + yogurt + fruit

🧬 The British Journal of Nutrition reports that a low-glycemic breakfast improves memory recall and reduces stress in students [source].

✅ 9. Use the “Brain Dump” Technique in the Exam Hall

Before starting the exam, quickly jot down:

• Formulas
• Dates
• Definitions
• Mnemonics

This frees your brain from the effort of holding onto them while reading the paper.

🧠 Cognitive load theory suggests that offloading working memory improves problem-solving during exams [source].

✅ 10. Visualize Success (Not Failure)

Close your eyes for 1 minute before the paper begins. See yourself:

• Opening the paper calmly
• Writing with flow
• Leaving with a smile

🧠 Visualization techniques activate the same brain circuits used during the actual task—boosting confidence and reducing panic [source].

🛑 What NOT to Do Before an Exam

❌ Don’t Cram

Last-minute cramming increases anxiety and rarely improves retention.

❌ Don’t Compare with Friends

Their confidence or panic doesn’t reflect your prep.

❌ Don’t Scroll on Social Media

Avoid the stress of “study reels” or toxic productivity content. It spikes anxiety.

🧘‍♂️ Hiron Sir’s Pre-Exam Routine (What I Tell My Students)

Here’s a routine I personally follow and recommend:

🗣 Real Student Story: Riya’s Calm Comeback

Riya, one of my 10th standard students, used to panic every time a teacher announced a surprise test. She’d tremble, forget everything—even faint once during revision.

We began incorporating 3 tools:

• Box breathing
• A nightly journal
• Visualization

By the time boards came, her confidence was rock-solid. After her science paper, she told me:

“Sir, I didn’t panic once. I actually enjoyed writing it.”

Now she’s helping juniors do the same.

🧩 Final Thoughts: Calm Is a Skill You Can Learn

If there’s one message I want you to take away from this, it’s this:

You don’t need to be fearless. You just need to be prepared—with tools that calm your body and mind when it matters most.

Your anxiety isn’t a sign of weakness—it means you care.
Let’s transform that into strength with strategy.

Stay calm. Stay steady. And walk in like you already belong there.
