1. Why Timed Simulation is Critical
Solving a math puzzle with unlimited time is vastly different from solving 60 questions under a strict 90-minute countdown with negative marking. Mock tests train your cognitive stamina, calibrate internal pacing, and desensitize you to countdown pressure.
- Throughput Rate: Total questions attempted divided by total minutes (aim for $\ge 0.75\text{ questions/min}$).
- Net Accuracy: Correct answers divided by total attempted (target $\ge 85\%$).
- Time Drain Index: Average minutes spent on questions answered incorrectly (must be under 45 seconds).
