Test-taking anxiety and score drops frequently result from poor time budgeting rather than lack of subject knowledge. Psychometric testing research indicates that over 40% of points lost on standardized tests occur because students spend disproportionate time on difficult early questions, leaving them forced to rush through or leave blank easier questions at the end of the test paper.
Practicing under an authoritative, unyielding exam hall clock conditions students to internalize their 'per-question budget'. By training with visual 15-minute and 5-minute milestones, candidates develop the discipline to abandon stubborn questions, bank secure marks, and preserve a mandatory 5-minute buffer for review.
