Direct answer
When stress rises, the problem may be access rather than storage. Attention gets pulled toward worry and physical arousal, so the brain has fewer resources for deliberate recall.
Train retrieval before pressure
Do not wait until the exam to discover whether you can retrieve information. Use closed-book questions, flashcards that require production, practice problems and short verbal explanations from memory.
Practise in realistic conditions
Occasionally work with a timer, mixed questions and limited notes. This creates familiarity with the sensations of performance and reduces the gap between study and testing.
Separate learning from performance
During learning, slow down and correct errors. During performance, follow a simple sequence: breathe, read, choose, answer, move on. Trying to relearn everything while under time pressure creates more noise.
Watch for wider problems
Persistent memory complaints, severe anxiety, major sleep disruption or changes in functioning should not be assumed to be a study-habit issue. Appropriate medical or psychological evaluation may be needed.
