You wouldn't put cheap fuel into a Ferrari before a race, so why are you eating potato chips and energy drinks before a 3-hour Physics exam?
1. The Breakfast Myth
If you have a 9 AM exam, you must eat breakfast, but it needs to be the right kind. Avoid simple carbs (pancakes, sugary cereals, white toast). These cause a massive spike in blood sugar followed by a crash 90 minutes later—exactly when you are midway through the exam. Eat complex carbs and protein: oatmeal, eggs, or whole-wheat toast.
2. Hydration and Brain Function
Even a 2% drop in hydration levels causes a measurable decrease in cognitive performance and memory recall. Keep a clear water bottle on your desk in the exam hall and take a sip every 20 minutes.
3. Omega-3s and Memory
In the weeks leading up to the exam, increase your intake of Omega-3 fatty acids (found in salmon, walnuts, and chia seeds). They are scientifically proven to improve memory consolidation and reduce neuro-inflammation caused by stress.
