The Impact of Immediate Self-Review Strategies on Performance in IGCSE Secondary Mathematics Examinations: A Metacognitive Approach

Abstract

In high-stakes examinations such as Cambridge IGCSE and A-Level Mathematics, students frequently lose valuable marks due to careless arithmetic errors, misinterpretation of questions, incorrect units, or incomplete workings, even when core concepts are understood. Traditional end-of-exam review often proves ineffective under time pressure and mental fatigue. This paper reviews the strategy of immediate self-review and correction right after completing each question or section, allowing real-time error detection and fixes that can significantly improve accuracy and final grades. Drawing on common examiner-reported mistakes in IGCSE/A-Level Maths, the study examines cognitive and practical benefits of this per-question review approach compared to bulk checking at the end. From a mathematics leadership perspective, the Head of Math discusses implementation in departmental teaching practices, curriculum integration, and student training. Complementing this, the HR perspective explores staff development, teacher training programs, change management, and fostering a culture of continuous improvement among educators to support such innovative exam techniques. Findings suggest that immediate review builds better metacognitive habits, reduces error propagation, and leads to higher achievement, while successful adoption requires strong instructional leadership and targeted HR-supported professional development.
