Mental Stamina for 95 Minutes

The LNAT Section A is not just an intellectual challenge — it is a test of sustained concentration. Ninety-five minutes of continuous, high-stakes reading and reasoning is mentally exhausting. Many candidates perform well on the first 6–7 passages but see their accuracy decline sharply in the final third. This lesson addresses the mental stamina challenge and provides practical strategies for maintaining peak performance throughout.

The Fatigue Curve

Research on sustained cognitive performance shows a predictable pattern:

Phase	Time (approximate)	Cognitive State
Warm-up	0–15 minutes	Getting into the rhythm; may feel slightly nervous
Peak performance	15–50 minutes	Fully engaged; highest accuracy and speed
Early fatigue	50–70 minutes	Concentration begins to waver; more effort required to maintain focus
Late fatigue	70–95 minutes	Significantly reduced concentration; higher error rates; decision fatigue
