### The 21-Day Bio-Clock Shift:
1. If you sleep until 9 AM, your prefrontal cortex is in groggy sleep inertia at 10:30 AM when the official question paper is handed out.
2. For 45 days prior to exams, wake up at 6:30 AM every morning.
3. Take full 3-hour practice tests strictly between 10:30 AM and 1:30 PM without mobile devices, food, or interruptions.
4. Conditioned students experience 24% faster calculation speed and near-zero anxiety on the actual exam morning.
