The exam is this morning.
Your heart might be beating faster than usual. Your stomach might be unsettled. There might be a particular quality of sharp alertness in your body.
This lesson is about working with that state rather than fighting it.
Yerkes-Dodson law: optimal performance requires moderate arousal — too little = flat, too much = overwhelmed
Reappraising exam anxiety as excitement (Alison Wood Brooks Harvard study) improves performance
The morning ritual: what to eat, what to do, what not to do
Power posing and embodied cognition: brief posture changes shift hormone levels
The Yerkes-Dodson law — one of the most replicated findings in performance psychology — shows an inverted U-shaped relationship between arousal and performance. Too little arousal (flat, disengaged, not caring) produces underperformance. Too much arousal (panic, overwhelm, flood) also produces underperformance. The sweet spot is moderate, engaged arousal — feeling sharp, present, and appropriately alert.
The anxiety you may be feeling this morning is not far from that sweet spot. The question is whether you can channel it rather than suppress it.
Alison Wood Brooks at Harvard conducted a fascinating study: students about to give an anxiety-producing speech were randomly assigned to say either "I am calm" or "I am excited." Those who reappraised their anxiety as excitement performed measurably better. Why? Because anxiety and excitement have nearly identical physiological signatures (elevated heart rate, heightened alertness, increased arousal). The difference is cognitive appraisal — whether the state is interpreted as threat or as opportunity.
The morning ritual:
- Eat breakfast: glucose is the brain's primary fuel. A balanced breakfast (protein + complex carbohydrate) maintains blood sugar stability for 3–4 hours — covering most exam durations. - Move briefly: 10 minutes of gentle movement (a walk, stretching) metabolises stress hormones and increases dopamine and norepinephrine, which improve alertness and cognitive flexibility. - Avoid phone: social comparison and news before an exam amplifies anxiety without adding value. - Review something easy and already known (not cramming — just a familiar summary) to prime access to material.
Find a comfortable position · Read slowly
This morning (or practice it now for the next exam):
Say aloud: "I am excited. I am ready. I know things worth knowing."
Take three deep breaths — in for 4, out for 8.
Roll your shoulders back. Sit or stand tall. The research on embodied cognition (Amy Cuddy and others) shows that posture changes influence stress hormones — broad, open posture for 2 minutes measurably changes physiological state.
Then: walk to the exam room as if you belong there. Because you do.
Nerves are not evidence of unpreparedness. They are evidence that you care. That caring, channelled, is part of what makes you perform. Claim it.
